How to solve the lighting fault light
In daily driving, fault lights on the car dashboard are one of the common problems, especially when the lighting fault lights (usually displayed as bulb icons) are on, which may mean that there is an abnormality in the vehicle lighting system. This article will combine popular topics and hot contents on the entire network for the past 10 days to analyze the reasons and solutions for lighting failure lights in detail, and provide structured data for reference.
1. Common reasons for lighting failure lights
A lighting fault light is usually related to the following issues:
| reason | Specific performance |
|---|---|
| Damage to the light bulb | The headlights are not on or blinking |
| Line short circuit or break | The lights are not lighted when they are on |
| Fuse blown | Multiple lights fail at the same time |
| Light control module failure | The light cannot switch on and off normally |
2. Steps to solve the lighting fault light
Here are the step-by-step solutions for lighting fault lights:
1. Check the status of the light bulb
First, confirm the specific headlights corresponding to the fault light (such as headlights, taillights, brake lights, etc.), and check whether the light bulb is damaged. If the light bulb goes black or the filament breaks, the same type of light bulb needs to be replaced.
2. Troubleshoot circuit problems
If the light bulb is normal, check whether the wiring connection is loose or corrosive. You can use a multimeter to measure the voltage to confirm whether the line is powered.
3. Check the fuse
Refer to the vehicle manual to find the location of the fuse of the lighting system and check whether it is fuseless. If it blows, replace the fuse of the same specification.
4. Diagnostic control module
If the above steps do not solve the problem, it may be a failure of the lighting control module. It is recommended to use a professional diagnostic instrument to read the fault code, or contact the maintenance personnel to deal with it.
3. Statistics on lighting failure problems of popular models (data in the past 10 days)
| Car model | Common faults | Solution |
|---|---|---|
| Toyota Corolla | Poor contact with taillights | Clean the lamp holder contacts |
| Volkswagen Golf | Headlight module failure | Replace the control module |
| Honda Civic | Frequent fuse blows | Check the line short circuit |
| Nissan Sylphy | LED daytime running light attenuation | Replace LED light set |
4. Suggestions for preventing lighting failures
To avoid frequent lighting failure lights, the following precautions can be taken:
1. Check the status of the headlights regularly, especially before long-distance driving.
2. Avoid using non-original light bulbs to prevent voltage mismatch.
3. Pay attention to protecting the lighting components when washing the car to avoid direct flushing of the high-pressure water gun.
4. Repair minor faults in a timely manner to prevent the problem from amplifying.
5. Professional maintenance vs. Self-processing
| Scene | suggestion |
|---|---|
| Simple light bulb replacement | Can handle it yourself |
| Line problems | Professional repair is recommended |
| Module failure | Must be professionally maintained |
Summary: Although the lighting fault light may be just a small problem, it is related to driving safety and should be dealt with in a timely manner. Through this article’s structured analysis and solutions, you can choose to repair yourself or seek professional help based on the specific circumstances. If the problem is complicated, it is recommended to go to a regular maintenance point for inspection as soon as possible to avoid safety hazards caused by lighting failure.
