The lights are dim, what should I do? What is the cause of the dim lights of the car

The right headlight of the car is dark and not bright on the left may be: 1. The tie iron of the right bulb is abnormal, and the circuit needs to be readjusted. 2. The bulb has reached a certain service life, so that the filament of the bulb has been aged, and the luminosity of the bulb has become dim.

3. If the battery output is unstable, it will also cause the headlights of the new car to be bright on the left and dark on the right. ”

Car batteries. Aging, reduced power supply or continuous power supply capacity. This situation is more common in cars that have been used for a certain number of years, and the same bulb is installed on other cars, which will be brighter than the car, and at this time, the dimming of the car lights may be related to the aging of the car battery.

2. Automobile lamp circuit aging. The current flows through the outer surface of the wire, and if the wire is aged, the surface of the metal core is aged, rough, the diameter becomes smaller, and the cross-section is uneven, which can easily cause excessive electrical loss of the wire, resulting in insufficient current reaching the bulb that can be effectively used, and the light will be dimmed. 3. The assembly is old.

The assembly is composed of a lamp cup, a cup base, a lampshade and other parts. A better assembly is a crystal headlight assembly. The assembly of other materials is more prone to yellowing, blackening, roughening, and darkening, so that the light is reflected by the lamp cup and suffers a lot of loss when passing through the lampshade.

4. Aging of bulbs. Of all the components, the deterioration of the bulb is the most common. Although car owners hope that the lights can be bright and durable, in fact, for standard power bulbs, the brightness cannot be as bright as searchlights, and the life span will not be very long.

The life of imported bulbs is slightly longer, generally more than 6 months, and can be used for more than 2 years with good maintenance. During the use of the bulb, the brightness of the bulb is not sufficient due to the oxidation of the contacts, the aging of the internal electrode virtual attack column, the volatilization of the filament, and the deposition of volatiles in the glass bulb. In general, if you notice that the bulb is a little bright, the bulb will be in the middle"Fogging"And it does not disperse for a long time, and the fog can still be seen after the lights go out, and after a long time, the inner wall of the bulb glass is blackened, then the filament has been seriously volatile, and its volatiles are affected by high heat when lit"Fogging"After cooling, it adheres to the inner wall of the bulb, affecting the luminous flux.

If the instrument indicator is not lit, first check the power supply fuse of the dashboard, and replace it if it is blown. Disassemble the dashboard, the lights are generally at the back of the dashboard, replace the lights that are not lit, and generally the individual lights are not lit to indicate that there is no problem with the fuse and wire, the main reasons are as follows

1. The light of the dashboard is damaged, and the light needs to be replaced in time;

2. If the power supply line of the dashboard is broken, there is an open circuit or short circuit, which will also cause the car dashboard to not light up;

3. If the power supply fuse of the car dashboard is broken, there will naturally be no power supply, and the dashboard will not light up.

Precautions in the use of the car dashboard:

1. When the indicator light is on, the odometer should be observed immediately, if the cumulative mileage reaches or exceeds l00,000km, the timing toothed belt must be replaced, otherwise the timing toothed belt may break, so that the engine can not work normally.

2. After replacing the new timing toothed belt, it is necessary to open the rubber plug outside the reset switch on the mileage dial, and press the reset switch inside with a small round rod to extinguish the timing toothed belt indicator.

3. After replacing the new timing toothed belt, remove the odometer and adjust all the readings on the odometer to the 0 position.

Summary. Hello dear! I am glad to answer your questions, I am a car problem solver, and I make the following for your questions:

Turn on the headlights, the instrument panel is darkened because of excessive power consumption, that is, the battery is not supplied enough. It may be that the battery performance is not good, it is recommended to go to the car repair shop to check the fault. Instrument panel for the installation of rigid slabs or structural parts of instruments and related devices.

According to the type, there are screen instrument panels, frame instrument panels, channel instrument panels, and cabinet instrument panels.

Pro-local suspicion, hello Tongshou! I am a car problem solver, and I make the following questions: turn on the headlights and the dashboard is darkened because of excessive power consumption, that is, the battery power supply is insufficient.

It may be that the battery performance is not good, it is recommended to go to the car repair shop to check the fault. Instrument panel for the installation of rigid slabs or structural parts of instruments and related devices. According to the type, there are screen instrument panels, frame instrument panels, channel instrument panels, and cabinet instrument panels.

The meter backlight enters the night working mode, so the light is dimmed.

When the driver turns on the lights, the computer will think that the light outside the car is too dark or it is dark (the driver will turn on the lights), so it automatically adjusts the instrument lights to make them darker. The purpose of this is to make the instrument light soft and not dazzling, and the driver's eyes will feel more comfortable and less fatigued, and improve driving safety.

Did the car start? If it is still dark after starting, it is a problem with the alternator. If the meter turns bright after starting, it means that the battery is losing power.

It is possible that the battery voltage is insufficient.

Your circuit is moving, you can adjust the brightness!

More and more people are pursuing night driving, especially when friends are in love, and friends basically like to go out at night. Especially for the vast majority of boys, they will suddenly feel embarrassed if the brake lights don't come on while driving. I don't know the solution.

That's when you have to think about the solution to dimming the headlights and the knowledge that the car can share with your friends. Let's solve the problem of brake lights not coming on.

Dim Lighting Solution, Slow Lighting Book: Causes.

1.If the brake bulb fails, replace the brake bulb.

2.Line faults, detect line problems.

3.No brake pedal pressed.

4.If the brake light switch fails, replace the brake light switch.

You can step on the two wires of the brake test switch. Basically there is no electricity, but the safety is broken. One of them had electricity, and the brake switch was broken. Basically, there's electricity, check the wires, and there's light bulbs.

Solutions for dim lighting,:Solution.

First, park the car on flat ground and turn off the engine to stop the car. Check the brake lights. Depending on the make and model of your car, unscrew the exterior lampshade, remove the lens cap, and enter the LED bulb.

Second, open the trunk and, if it's a truck, pull the baffle down. Take care to avoid electric shock and press the label on the plug to separate the keybook optics.

Finally, unplug the socket, turn off the left light first, then turn off the right LED light, and replace the burned LED light with a lamp of similar size and style purchased from the auto parts store. Insert the bulb, fix it in the corresponding position, and reassemble it in the reverse process of the above process.

Shaw told his friends that the headlights were too dim. Have friends learned? I hope to help my friends! Let friends go out again to prevent this unnecessary embarrassment. For more information about the car, please follow this **. The excitement continues!

Millions of car purchase subsidies.

<> "Cars have almost become a means of travel now, and the old drivers who deal with cars every day are also very concerned about their cars, and they are worried about whether something is wrong if the slightest situation is wrong. For example, the car lights that I am going to talk about today, especially when driving at night, it is easy to detect the brightness and darkness of the lights. However, if there is a problem and take it for repair, it is too much of a toss, so it is better to take good care of the lights on a regular basis to make the lights in the best condition.

Today we have summarized a list of lamp maintenance rules to see if you usually do it!

1. Test the lights.

Sometimes when driving on the road, you will see that some of the car's brake lights are on one side, or the low beam lights are on and off. These veteran drivers are not ready to test their lights, which are important for information-conveying lights, such as brake lights, and lamps used for lighting, such as low beams. In addition, there are fog lights, tail lights, hazard warning lights, turn signals, etc., all of which need to be tested to see if they can work properly.

The brightness of the light and the deviation of the illumination angle also need to be paid attention to, and if there is a problem, the bulb should be changed or corrected in time.

2. Replace the bulb.

The light bulb of the car also has its own lifespan, the life of halogen lamps is about half a year, the life of xenon lamps is about five years, and the life of LED lamps is about four years. In the process of use, there are contact oxidation, filament volatilization, parts aging and other problems of caution, even if the bulb can still be on, but it will definitely be darker than new, and it will affect safety when driving at night.

Some cars have a light bulb on one side and a bulb on the other, and the owner thinks that one is still on anyway, so there is no need to change it. However, in order to have a better view at night, it is recommended to replace the dimmed bulbs with different brightness. However, it should be noted that the purchase of car lights should go to regular merchants, otherwise it is very unsafe to buy inferior car lights.

3. Check the line.

If the wiring of the lamp is aging or the wire is too thin, the resistance will increase and affect the current, causing the brightness of the lamp to dim. Therefore, old drivers should regularly check whether there is a problem with the line of the headlights, otherwise the line is overheated, and it is easy to cause open fire accidents and affect driving safety. However, the inspection line cannot be disassembled and checked at home without permission, and it is best to go to a professional repair shop to ask a professional to help check it.

Fourth, lampshade care.

The lamp cover of the car will be made of special materials to ensure its sealing, but when the lamp bumps and cracks, the air will enter, and it is necessary to go to the repair shop for repair in time, otherwise the lamp will not work properly. In the process of driving, the lampshade of the lamp will also be covered with a layer of dust, mud and other dirt, and so on after drying, it will affect the lighting effect of the lamp, to clean the lampshade in time, keep the wide and clean.

When washing the car, you should also pay attention to drying the water on the headlights and the engine compartment, otherwise too much water will enter the inside of the lights, and over time, not only the headlight cover will be blurred due to water vapor, but also damage the lights.

It is generally divided into the following situations:

1. Dust accumulates on the astigmatism glass or reflector. For such a problem, it can be solved by wiping it with a dry and clean rag;

2. The surface of the bulb glass is black, the luminosity of the bulb is lower than the specified requirements, and the bulb filament is not located on the reflection focus and causes astigmatism. Maybe it's because the bulb is broken, and it is recommended to replace the bulb;

3. Poor tie ride. It is recommended to check whether the connecting wire and the tie wire joint are loose, if it is loose, the rust should be removed, and it should be fixed firmly after sandpaper;

4. The wire is too thin, the resistance increases, and the wire is overheated, which affects the conductivity. For headlight wires that are too thin, standard wires should be replaced.

It is generally divided into the following situations:

1. Dust accumulates on the astigmatism glass or reflector. For such problems, a wipe with a clean rag can be solved;

2. The surface of the bulb glass is blackened, the luminosity of the bulb is lower than the specified requirements, and the bulb filament is not located on the reflection focus and causes astigmatism. Maybe the bulb is broken, it is recommended to replace the bulb;

3. Those who build iron and do not have limbs are good. Such a problem is very simple, that is, the contact is poor, it is recommended to check whether the connecting wire and the tie wire joint is loose, if it is loose, the rust should be removed, and it should be fixed firmly after polishing with sandpaper;

4. The wire is too thin, the resistance increases, and the wire is overheated, which affects the conductivity. For the headlight wire is too thin to build a stool, the standard wire should be replaced.

The solutions to the car headlights are not bright enough: wash the headlights with soapy water, apply a little toothpaste to the car cloth, wipe the surface of the headlights with a soft cloth, etc. The reason why the car lights are dirty and blurry is because the surface of the headlights is made of polycarbonate, which is actually plastic, and after being exposed to the wind and sun, it will be slowly corroded and scratched by dust and small stones in the air, and even some yellow stains that are difficult to clean, resulting in the lights are not bright.

Tip 1: toothpaste; You'll need a towel and sponge before you start. First scrub the surface of the headlight with a damp cloth, then apply the toothpaste to the surface of the headlight, use a sponge to beat the toothpaste, and then wipe it clean with a towel. Of course, it's okay to replace toothpaste with soapy water.

Trick 2; soft towels; This kind of answering trick focuses on your usual maintenance, rather than making the headlights new at one time. When you don't usually drive, you can carry out this inventory and maintain it very simply.

Tip 3: Change the light bulb; If you use the above two methods, the headlight light is still very dim, then it is not the reason for the lampshade, then you need to replace the headlight bulb. The headlight bulb is not as bright and expensive as possible, but moderation is fine.

The cleaning method is as follows: 1. Clean the headlamp with soapy water: laundry detergent and laundry detergent are very corrosive, it is best to use soapy water to clean, soapy water is a weak alkaline substance, not corrosive, its nature is mild and has a high cleaning ability, not only can remove the dirt on the surface of the headlight, but also increase the brightness of the headlight.

2. Apply a little toothpaste on the car cloth: wipe the car lights in a circle, if you find a blur or scratch, you can add some toothpaste to wipe hard, and then you will find that the car lights gradually become transparent, wipe them almost clean with water, and then dry them with a soft cloth or paper towel.

3. Wipe the surface of the headlights with a soft cloth: After a long time of use, the surface of the headlights often accumulates dust, particles and other impurities, and the car wash cannot clean this impurity. In fact, before using the car in daily life, you can use a rag to wipe off the floating ash to prevent the dust from accumulating more and more and even penetrating into the inside of the headlights, affecting the lighting effect.
