Nissan Altima Auto Lights Not Working? The 25 Correct Answer

Windshields with small cracks or chips can usually be repaired if they are small enough that you can avoid replacing the light sensor.

If your windshield has a crack larger than a dollar bill, then it really should be replaced along with all the hardware installed on the windshield.

Light sensor systems are available on the market, but an OEM reinstall is the best way to ensure they are working properly.

If installed poorly, the backlight detection may turn on the lights when not needed, draining the battery, or not turn on when needed. A sensor failure will cause the headlights to come on in broad daylight when they don’t need to be turned on, or the ambient light sensor could be worn out. In any case, replace either the entire windshield or the headlight sensors.

Car Guides Car Questions and Answers: If you have automatic headlight adjustment, use it. Should we make it extra difficult to switch to the off position? Light control in the car. Dreamstime/TNS

Q: I’ve seen so many cars drive with their headlights off at night and I can’t help but wonder. There’s an automatic setting for headlights, and it seems like that should be the default so we don’t have to worry about turning the lights on and off.

Should we make it extra hard to switch to the off position? Also, there is no warning sign on the dashboard when the headlights are off in the evening. Is that something we should suggest to automakers?

— XW, St. Charles, Illinois.

A: Not all vehicles have automatic headlights, especially older models. But I agree that if your car is so equipped, you should use the automatic setting. Although there are no dashboard reminder lights to indicate that the headlights are off, this task often falls to oncoming motorists who flash theirs.

Q: I read your two columns about the traffic light in the back window of the car. I put a toy traffic light in the back window of my car so it’s most likely my vehicle that was seen driving in the Chicagoland area. I live in Schaumburg and installed my old toy traffic light Buddy L in the back window of my car in the 1980’s and moved it around when replacing my cars.

I put this in my car long before cars had the rear third brake light. The yellow light comes on when I take my foot off any pedal. Red lights up when I’m braking and green when I’m accelerating. I use micro switches on the pedals. I replaced the old Christmas light bulbs with LEDs. A police officer stopped me years ago, but he just wanted to know where he could get one. I’m still looking for another toy traffic light so I can add one to my other car.

— LA, Schaumburg, Illinois.

A: Very smart. I assume you’ve looked at hobby shops, particularly those that specialize in electric trains and accessories. I did some surfing and found one over at Bed Bath and Beyond that you might be able to hack. The brand is Theo Klein and even has Walk/Don’t Walk lights.

Q: B.K. in Chicago noticed how regenerative braking drives almost with one foot. Your left foot is for clutch and parking brake only. If you use both feet in an automatic transmission vehicle, you can press both pedals at the same time. This guarantees a much longer braking distance in a panic situation.

What I hate are the flickering brake lights in heavy traffic. You have no idea what the car in front of you is really going to do. Or the glaring brake lights when accelerating. It seems two-footers are justifying their tailgating causing the rolling yo-yo traffic jams. As heavy as Japan’s traffic is, it’s frustrating because of the uniform, consistent behavior of drivers.

— T.S., La Grange, Illinois.

A: Drivers with two feet are sometimes lazy and tend to keep their left foot on the brake pedal. Not only does this send the wrong signal to following cars, it also sends the wrong signal to the vehicle’s operating systems. The engine and transmission control modules rely on signals that the brakes are being applied to make important decisions. In addition, premature brake wear is likely. The only time I use both feet is trail braking at the circuit.

Bug fix when switching to 4WD in F-150

By Brad Bergholdt, Tribune News Service

Q: I have a 2013 F-150 4×4 (bought new) with less than 19,000 miles on it. If I switch to all-wheel drive under load, e.g. B. on a steep incline, there is a loud bang under the truck. Is this a problem? If I anticipate the shift and make it on the flat in front of a hill, no problem. The mechanic at the nearby dealership who checked it couldn’t get it to respond similarly (no surprise given the flat paved roads nearby). But if I forget to anticipate when I’m towing my 22-foot camper up a grade on a gravel road and switch to 4WD mode for extra traction, the resulting noise is worrisome.

– John

A: John, your truck is equipped with an “electronic on the fly” shift system that allows it to shift from 2 wheel drive (2WD) to 4 wheel drive (4WD) at any speed in the high range and below Shifting 2WD to 4WD in low range 3 mph with transmission in neutral. The transfer case includes an electronically controlled clutch that is used to synchronize the speed of the front driveline with the rear driveline during shifts from 2WD (2H) to 4WD high (4H).

The second half of the shifting process uses the IWE (Integrated Wheel End) system, consisting of spring-loaded vacuum hubs that connect or disconnect each front wheel hub to the outer axle. Engine vacuum is supplied to each hub or not via a solenoid controlled by the transfer case control module. This is perhaps the slower of the two systems. Checking the vacuum reservoir and hoses for leaks can be considered.

I believe the transfer case clutch does the job well whether you’re under load or not, but the smooth shifting of the hubs is probably another matter. Assuming that the transfer case shifts before the hubs complete, a significant force would be exerted on the translatable/engaging hub mechanism when the drive train is under load. Maybe one hub will engage first, and the bang is the internals of the front axle slamming hard as the second engages? This is not good and should be avoided!

It can be difficult to always predict when 4WD operation is required for the road or trail ahead, and it is not advisable to engage 4WD on dry roads. If you’re surprised by the need to shift from 2WD to 4WD up a hill, perhaps ease off the throttle briefly to allow the shift to complete before pushing back down, or better yet, stop?

This brings back memories of my 1951 Chevy pickup with vacuum-powered wipers. Climbing a long incline in the rain, I occasionally had to let off the gas for a few swipes!

Excerpted from an old thread, don’t know if it’s only for 5.5s, but I know it’s for dealers only, not DIY.

Headlight lighting delay

(time the headlights stay on after leaving the vehicle if the headlights are in the “Auto” position)

Mode 1: 45 seconds

Mode 2: No delay

Headlights are not only an important safety component on your vehicle, but also a piece of equipment required by law. Not using your headlights when driving at night requires an expensive ticket, and you can even get a repair ticket if one of your lights isn’t working properly.

Headlights are designed to give you maximum visibility when driving your vehicle. They illuminate the road ahead when it’s dark and can even be used to improve visibility in adverse weather conditions. Equally important, headlights make your vehicle visible to oncoming traffic, which is vital to your safety on the road.

To use your headlights, you must first turn them on. This process will vary slightly depending on the make and model of your car; but for the most part, headlight operation is fairly similar in each vehicle. Using your headlights is remarkably easy and only takes a few seconds.

Part 1 of 4: Identify the headlight components

Step 1: Locate the headlight controller. The headlight controls are almost always positioned in one of two places.

The first place you can find the controls is on one of the levers protruding from either side of the steering column. The second likely location is on the dashboard to the left of the steering wheel.

If your headlight control isn’t in one of these two places, you should be able to find it somewhere on the dashboard, control center, or steering wheel.

Tip: The headlights are usually accompanied by an icon of an upside down lightbulb or a sun. Look for this icon to find the headlights in your car.

Step 2: Find out the meaning of the headlight symbols. In order to use the correct headlight setting, you need to identify the different headlight symbols.

Your headlights will automatically switch to the off position, which is usually a symbol of a blank circle or the word “off”. There will also be an icon of two lights pointing in opposite directions, indicating the parking lights or daytime lights. Finally, there will be an icon of a large light pointing to the left (this looks like the letter “D” with lines protruding from it) indicating the main headlights.

If your vehicle is equipped with automatic headlights, these will appear with the word “auto” or the letter “A” in an inverted headlight.

Tip: If your vehicle has fog lights, the icon will be near the main headlight controls, but not in line with the other controls. The fog lights are identified by a symbol similar to the headlight symbol, but with the light directed downwards.

Part 2 of 4: With the headlights

Step 1: Turn on the headlights. Rotate the headlight switch until it is on the setting you want to use. Each setting has a notch to make it clear the switch is in the right place.

Tip: If you turn the headlight switch to the automatic setting, the headlights will automatically turn on or off based on the current light conditions outside the vehicle.

Step 2: Turn off the headlights. After driving, make sure to turn off the headlights. To do this, simply turn the headlight switch back to the original “off” position.

Warning: Leaving your headlights on after turning off your vehicle will begin to drain the battery. There is a limited amount of time your lights can stay on before the battery dies. To avoid this, your vehicle will beep when the lights are on but the ignition is off.

Part 3 of 4: Using the high beam and fog lights

Step 1: Turn on the high beams. The high beam provides extra light when it is very dark outside.

To turn on the high beams, push the turn signal lever forward or pull it toward you (depending on your vehicle) until it clicks. Return the lever to its original position to turn off the high beam.

When the high beams are on, a blue icon similar to the headlight icon will illuminate on the instrument panel.

Warning: While high beam improves your vision, it creates intense glare that reduces visibility of your surroundings. Always turn off the high beams when there is oncoming traffic or when you are directly behind another vehicle.

Step 2: Turn on the fog lights. The fog lights can be used in addition to the headlights to improve visibility in fog, fog or rain.

To turn on the fog lights, flip the fog light switch or press the fog light button (depending on your vehicle). This switch or button is located directly next to the headlight control.

Part 4 of 4: Maintaining your headlights

Step 1: Check the function of your headlights. To ensure safety and avoid fix-it tickets, you should regularly check that all your lights are working.

The best way to do this is to have someone you know stand in front of your vehicle while you switch between the different headlight settings. Make sure they check both headlights.

If you don’t have anyone to help you with this task, you can park your vehicle in front of a solid wall and watch the reflection of your lights while you change the settings.

Warning: If you find that one or more of your headlights are not working, you should have them replaced immediately.

Step 2: Pay attention to headlight warnings. When your headlight system fails, a warning light will usually illuminate on the control panel.

This light is often a blinking headlight indicator, a headlight indicator with an “X” through it, or a headlight indicator with an exclamation mark next to it. If you notice a headlight warning light, you should contact a certified mechanic, e.g. B. one from Vermin Club to inspect the system.

Tips: If you notice a headlight icon illuminating on the instrument panel, make sure it is a warning light and not the high beam indicator.

Using your headlights is very simple. After a few trips in the car, turning the headlights on and off becomes second nature. Remember to regularly check your headlights for proper operation and clean your headlights to ensure the best visibility while driving. If you are having problems with your headlights not working properly, a Vermin Club certified mechanic can come to you and diagnose the problem.

The system has two functions: twilight detection automatically switches on the headlights when the ambient light decreases; Front wiper connectivity automatically turns on the headlights when the wipers are used in the rain. These two features make it easier for other drivers and pedestrians to notice your vehicle in the rain or at dusk when accidents may occur.

In addition to the role of headlights at night, the system adds the benefit of making your vehicle more visible to others around you when it’s raining or at dusk. These early lighting features were known as “Considerate Lighting”. It is characterized by the fact that it can switch on the headlights in certain driving scenarios compared to conventional automatic lighting systems.

More and more models in the new car market have so-called automatic headlights as standard.

In this guide, we explain exactly what automatic headlights are, how they work and just how worthwhile having them on your next vehicle.

Automatic headlights are like all the other headlights you get at the front of the car, except they activate automatically when the car is on and it’s dark, without the driver having to press a manual switch.

They stay off in clear conditions and during the day, but if it’s later in the day or the car is driving into a dark place like a tunnel, for example, the automatic headlights can be activated and deactivated accordingly.

Cars with automatic headlights can be turned on or off manually by the driver using the car’s controls if he so desires. But if the driver chooses the headlights to run automatically, as by default (this setting is usually labeled “auto”), then they should be fast and intelligent enough to do the job for the driver.

How do automatic headlights work?

Automatic headlights typically use photoelectric sensors embedded in the instrument panel around the base of the windshield.

These sensors rely on the ambient light level rather than the driver’s perceived vision. As a result, automatic headlights may turn on at times when the driver does not deem it necessary. Alternatively, they may not turn on immediately when conditions get darker or otherwise visibly worse, so drivers should be prepared to manually activate their headlights if deceleration occurs.

Like other automated car convenience features – like automatic windshield wipers, automatic parking assistance and automatic emergency braking – automatic headlights have benefited in recent years from how quickly manufacturers have advanced sensor technology in recent years.

Are automatic headlights worth it?

Automatic headlights are a nice little luxury when they come standard on the new car you’ve decided on. But what if it’s not an automatic option, but you can add it as an optional extra? Will they feel like a worthwhile investment?

That’s ultimately your decision, of course, but the only thing likely to influence your decision is considering how much it typically costs to add automatic headlights to a select car.

The price of adding automatic headlights to your selected car can vary wildly as it is either an individual option or, more likely, part of an option package (e.g. Peugeot’s visibility package).

If you consult your owner’s manual it will tell you how to disable the auto light feature…. turn the ignition on (with or without the engine running) and simply press the dome override button 4 times within a 5 second period and the auto function is deactivated; it will notify you of the deactivation with a beep. Repeating the process reactivates the automatic function. It is also reactivated the next time the ignition is switched off and on. In manual mode, the light switch is used to select the lighting mode.

Despite the many advances in automotive technology, the basic lighting in your car has remained largely unchanged. When your car’s lights won’t turn off, the troubleshooting process is pretty much the same as it has been for many years.

Dealing with headlights that cannot be switched off

First, don’t leave your car overnight with the headlights on. You will drain your battery and you will have to deal with the added headache of a dead battery in the morning.

Remove the headlight fuse

The easiest solution is to remove the headlight fuse until you have time to fix the problem. You can find the fuse under the dashboard or in a fuse box under the hood. There is a diagram on the fuse box cover that indicates which fuse relates to each part of the electrical system.

Locate the headlight fuse and carefully remove it.

Remove the headlight relay

Alternatively, you can remove the headlight relay if it is more accessible than the fuse.

The relays are the larger, rectangular boxes next to the fuses in the fuse box. They handle much higher electrical loads than the switches, so removing the relay breaks the circuit between the battery and the headlights in the same way removing the fuse does.

Disconnect the battery

If that doesn’t work, or you can’t find the correct fuse or relay, then disconnect the battery cable at the battery post.

Locate the battery negative terminal; it is the black one. If in doubt, there is also a (-) sign next to the battery pole. Loosen the nut holding the terminal and pull the terminal off the battery.

After removing, make sure that the cable cannot accidentally touch the negative terminal of the battery to prevent the current from flowing again. Remember that disconnecting the battery may erase settings in your car’s electronic control unit, which will take some time to reset after reconnecting the battery.

Troubleshooting common problems with faulty headlights

Typically there are 5 components in a car’s light circuit.

Battery fuse switch wiring

If your headlights are on and won’t turn off, the battery, fuse, and lightbulbs are working properly. The problem then becomes isolating either the switch or the wiring.

Let’s look at each of the possible causes:

1. Defective headlight switch

Try turning off the headlights before turning off the ignition. Some modern vehicles have lighting systems that are designed to stay on for a short time after the ignition is turned off. If the lights go out before you remove the key, then your problem is the module that is delaying the lights turning off.

If your vehicle is equipped with daytime running lights, the module that controls the system can be deactivated by applying the parking brake.

If the lights stay on with the parking brake on, you can try replacing this module to fix the problem. It is also possible to completely remove the module so that the function is permanently disabled.

Your headlight switch may also be shorted, causing heat build-up. If the heat melts the insulating covering around the wires or the plastic in the switch mechanism, the wires can make contact, completing the circuit and causing your headlights to stay on.

2. Defective headlight relay

Related to the headlight switch is the relay. The relay is a magnetic switch that can burn out.

Since similar relays are used for different systems in the circuit, you can try another relay identical to the headlight relay and test the headlights. If the headlights go out, you can buy a replacement relay to solve your problem.

3. Defective daytime running light module

For vehicles equipped with a DRL module, the checks required to test for this as a potential issue are a bit more complex.

The relay connected to the daytime driving module takes input from a variety of sources in your vehicle. These sources include the parking brake, headlight switch, one or more diodes, and indicator lights on your dashboard.

If you can read a schematic and have access to a test light and multimeter, you can check the continuity of the various circuits and components. But unless you’re a seasoned DIY enthusiast or auto electrician, it’s best to leave it to the experts to determine exactly which component is defective.

4. Defective light sensor

If your vehicle is equipped with automatic headlights, there is a sensor on the front of the car that turns on your headlights when the sun goes down. These sunlight sensors are located either in the center of the plastic cover under your windshield or under the windshield near your rear view mirror.

A quick way to check if this module might be the answer to your question; “Why don’t my headlights go out” means to move the headlight selector switch from Auto to Off or “0”.

If the headlights go out, you have located the problem.

Are the car brake lights on when the car is off?

When the taillights are on, we know the battery, fuse and bulbs are working, leaving switches and wires as potential culprits.

5. Stuck brake light switch

The brake light switch is located under the dashboard next to the brake pedal. Since the switch is open while driving and closed when the brake pedal is depressed, we can assume that the switch is stuck in the closed position.

To check this, locate the brake switch and note if the brake lever moves in unison with the brake when pushed. If the switch stays stationary, you can be sure that it is contributing to your problem.

There is a lot of dirt and moisture in the footwell around the pedals and switches can stick. Use a rag to clean the switch of any oil or dirt that may be preventing the switch from moving.

Disconnecting the switch confirms that it’s the problem if the lights go out when you unplug it.

6. Faulty brake light switch

If that doesn’t work, try disconnecting the switch. If that works and the brake light goes out, replacing the switch should solve the problem.

7. Shorted wiring

If disconnecting the switch doesn’t fix the problem, you may have frayed wiring causing a short.

The blinker stays on

Leaving your turn signals on can pose a serious safety issue. It can either keep blinking or just stay on without blinking. If your turn signal stays on after the turn signal lever returns to its center position, you may be dealing with a faulty flasher relay, a faulty turn signal switch, or possibly a grounded wire.

The indicator may only remain illuminated on one side. This may indicate a blown bulb on the other side. But it is usually accompanied by rapid blinking. Replacing the faulty bulb confirms the diagnosis.

8. Fixing a faulty turn signal relay

The turn signal relay is usually located under the dashboard. If the turn signals go out after removing the relay, replacing them may solve the problem.

9. Repairing a faulty turn signal switch

There is a spring in the turn signal that returns the switch to the off position when the steering wheel is centered after a turn.

If the spring is worn or broken, replacing it will solve the problem of keeping your turn signal on.

10. Grounded turn signal wiring

If the turn signal switch and relay are not the problems, it is very likely that the wiring has frayed and is shorting the circuit.

The danger of a short circuit is that it can drain the battery, damage components and, in the worst case, cause a fire. A sure sign you have a short to a grounded wire is if you remove the turn signal fuse and the lights stay on.

If you are inexperienced in dealing with worn wiring, your best bet is to remove the turn signal bulbs and take your car to an auto electrician to have the problem professionally repaired.

frequently asked Questions

How long does it take for the interior lights to drain the battery?

Depending on the age of the battery and how many lights are on, it can take anywhere from 4 to 8 hours for a car’s battery to drain.

Does the interior light turn off automatically?

Yes, the interior lights turn off automatically unless you have flipped the switch to the permanently on position. In this case, the lights will stay on until you turn them off. Some modern cars have a sensor that turns off the interior lights after a while if the vehicle hasn’t started. This is done to ensure that the battery is not drained.

How do I turn off the dome light in my car?

The dome light switch can be accidentally bumped or misadjusted. Therefore, check its location first before proceeding to the next troubleshooting step. Opening and closing the doors can trigger the dome light and will normally turn off once the vehicle has been driven for a short period of time.

Why won’t my car’s interior light go out?

The interior light switch may have been set to the always-on position, or the door switch may be defective and need to be recalibrated or replaced.

My parking lights don’t go out after I turn off the engine

Some cars have a parking light feature that illuminates the parking lights by operating the turn signal on one side of the vehicle. The parking lights are switched off by resetting the turn signal to the middle position.

Some European cars are known to have problems with the rear headlight leveling sensor causing the parking lights to stay on. Replacing the sensor fixes the problem.

Why should your car’s headlights stay on after the ignition is turned off?

Some modern cars are equipped with a delay feature that can take a few minutes for the headlights to turn off after the engine is turned off.

What can I do if my car’s headlights won’t turn off during the day?

You should check if your sunlight sensor is working. When working on the windshield or windshield wipers of a car, the sun sensor is often left unattached. Alternatively, you can also select the off position on the headlight switch if it was set to automatic.

Conclusion

There are many reasons why the light stays on when a car is off. But like most electrical problems, finding a solution can be frustrating. We hope you have found the advice and tips we have shared in this article useful when your car lights won’t go out.

5. The headlight socket is corroded On many vehicles, the headlight is a light bulb that plugs into a socket where electrical connections are made. If these connections are loose, there is a bad ground in the circuit, or moisture has gotten in, the headlight socket can corrode. This can initially cause a headlight to go on and off, or go out once and not come back. 4. Headlight wiring is compromised Vehicle wiring is built to last, but it can also be an enticing chew toy for rodents. Perhaps the vehicle’s previous owner felt able to rewire the headlights and they have not worked properly since. If you suspect that the wiring is the cause of your problems with your headlights, we recommend that you have it checked by a certified professional at your local authorized dealer.

Headlights are not only an important safety component on your vehicle, but also a piece of equipment required by law. Not using your headlights when driving at night requires an expensive ticket, and you can even get a repair ticket if one of your lights isn’t working properly.

Headlights are designed to give you maximum visibility when driving your vehicle. They illuminate the road ahead when it’s dark and can even be used to improve visibility in adverse weather conditions. Equally important, headlights make your vehicle visible to oncoming traffic, which is vital to your safety on the road.

To use your headlights, you must first turn them on. This process will vary slightly depending on the make and model of your car; but for the most part, headlight operation is fairly similar in each vehicle. Using your headlights is remarkably easy and only takes a few seconds.

Part 1 of 4: Identify the headlight components

Step 1: Locate the headlight controller. The headlight controls are almost always positioned in one of two places.

The first place you can find the controls is on one of the levers protruding from either side of the steering column. The second likely location is on the dashboard to the left of the steering wheel.

If your headlight control isn’t in one of these two places, you should be able to find it somewhere on the dashboard, control center, or steering wheel.

Tip: The headlights are usually accompanied by an icon of an upside down lightbulb or a sun. Look for this icon to find the headlights in your car.

Step 2: Find out the meaning of the headlight symbols. In order to use the correct headlight setting, you need to identify the different headlight symbols.

Your headlights will automatically switch to the off position, which is usually a symbol of a blank circle or the word “off”. There will also be an icon of two lights pointing in opposite directions, indicating the parking lights or daytime lights. Finally, there will be an icon of a large light pointing to the left (this looks like the letter “D” with lines protruding from it) indicating the main headlights.

If your vehicle is equipped with automatic headlights, these will appear with the word “auto” or the letter “A” in an inverted headlight.

Tip: If your vehicle has fog lights, the icon will be near the main headlight controls, but not in line with the other controls. The fog lights are identified by a symbol similar to the headlight symbol, but with the light directed downwards.

Part 2 of 4: With the headlights

Step 1: Turn on the headlights. Rotate the headlight switch until it is on the setting you want to use. Each setting has a notch to make it clear the switch is in the right place.

Tip: If you turn the headlight switch to the automatic setting, the headlights will automatically turn on or off based on the current light conditions outside the vehicle.

Step 2: Turn off the headlights. After driving, make sure to turn off the headlights. To do this, simply turn the headlight switch back to the original “off” position.

Warning: Leaving your headlights on after turning off your vehicle will begin to drain the battery. There is a limited amount of time your lights can stay on before the battery dies. To avoid this, your vehicle will beep when the lights are on but the ignition is off.

Part 3 of 4: Using the high beam and fog lights

Step 1: Turn on the high beams. The high beam provides extra light when it is very dark outside.

To turn on the high beams, push the turn signal lever forward or pull it toward you (depending on your vehicle) until it clicks. Return the lever to its original position to turn off the high beam.

When the high beams are on, a blue icon similar to the headlight icon will illuminate on the instrument panel.

Warning: While high beam improves your vision, it creates intense glare that reduces visibility of your surroundings. Always turn off the high beams when there is oncoming traffic or when you are directly behind another vehicle.

Step 2: Turn on the fog lights. The fog lights can be used in addition to the headlights to improve visibility in fog, fog or rain.

To turn on the fog lights, flip the fog light switch or press the fog light button (depending on your vehicle). This switch or button is located directly next to the headlight control.

Part 4 of 4: Maintaining your headlights

Step 1: Check the function of your headlights. To ensure safety and avoid fix-it tickets, you should regularly check that all your lights are working.

The best way to do this is to have someone you know stand in front of your vehicle while you switch between the different headlight settings. Make sure they check both headlights.

If you don’t have anyone to help you with this task, you can park your vehicle in front of a solid wall and watch the reflection of your lights while you change the settings.

Warning: If you find that one or more of your headlights are not working, you should have them replaced immediately.

Step 2: Pay attention to headlight warnings. When your headlight system fails, a warning light will usually illuminate on the control panel.

This light is often a blinking headlight indicator, a headlight indicator with an “X” through it, or a headlight indicator with an exclamation mark next to it. If you notice a headlight warning light, you should contact a certified mechanic, e.g. B. one from Vermin Club to inspect the system.

Tips: If you notice a headlight icon illuminating on the instrument panel, make sure it is a warning light and not the high beam indicator.

Using your headlights is very simple. After a few trips in the car, turning the headlights on and off becomes second nature. Remember to regularly check your headlights for proper operation and clean your headlights to ensure the best visibility while driving. If you are having problems with your headlights not working properly, a Vermin Club certified mechanic can come to you and diagnose the problem.
