The methods for repairing scratches on car lights are: 1. Polish with scratch wax; 2. Grind with toothpaste, then use a clean towel to rub in a circular motion. The functions of car lights are: 1. Turn on the turn signal to alert following vehicles and reduce rear-end collisions; 2. Improve visibility of road conditions and enhance driving safety; 3. Inform vehicles behind that you are braking and to slow down; 4. Turn on hazard lights during temporary parking, emergencies, or poor visibility due to bad weather to alert passing vehicles. The maintenance methods for car lights are: 1. Regularly check the lamp cover to avoid water droplets; 2. Replace car lights periodically; 3. Adjust the height of the lights properly; 4. Use high-quality bulbs when replacing car lights; 5. Prevent foreign objects from hitting the car lights.
I've also encountered scratches on car headlights before, so don't rush to replace them right away. For minor surface scratches, you can try using toothpaste. Apply it to a soft cloth and polish repeatedly to remove them, similar to how you'd treat scratches on a phone screen. If the effect isn't noticeable, head to an auto parts store and buy a specialized headlight restoration kit. Follow the instructions to polish and then apply an anti-UV coating—it takes about 20 minutes to complete. For deeper scratches, it's best to use a professional polishing machine, but if you're handy, you can buy a set of sandpaper and gradually polish from coarse to fine grit, then fill the grooves with resin. When parking, keep your car away from branches and walls, and avoid using hard-bristle brushes on the headlight covers when washing. Regularly applying car wax can help prevent new scratches. After restoration, check the light transmission rate. If the scratches are too severe, it's safer to replace the headlight cover.
