Replace the lampshade directly, but it is still recommended that you clean it yourself first, and use polishing if it is more serious. When parking, park the car in an area where the sun does not shine directly, and park in the shade as much as possible, because the most important factor for the headlights to turn yellow is exposure, and there is also the usual need to clean the headlights often and clean them in the sales market, but pay attention to using soft cloth and weak alkaline water.

When the headlights turn yellow, the method of cleaning them is to wipe them with a soft cloth and wash them with soapy water.

Many friends will only wipe the headlights when they wash the car. When I feel fine, I can use a rag to wipe the floating dust twice to prevent the accumulation of stubborn dirt.

During the wiping process, do not use a rough rag, as wiping hard may not work.

How to maintain car headlights

1. Check the tightness of the headlight: If water vapor invades the headlight, the service life of the bulb will be reduced. According to this note, check the tightness of the headlamp. If the seal between the lens and the mirror is damaged, replace it immediately.

2. Clean the mirror: When the mirror of the semi-enclosed headlamp turns black and the luminosity decreases, it should be replaced. If there is only dust on the mirror, it can be blown clean with compressed air and not replaced.

For reflectors that cannot be blown clean, if the coating material of the reflector is chrome-plated, due to the high hardness of deerskin, you can dip the deerskin with absolute ethanol (content of more than 95%), and gently and delicately wipe it in a spiral shape from the inside to the outside of the reflector.

Tips for cleaning yellowing headlights: wash them with toothpaste, wipe them directly with soapy water, polish them with yellowed headlights, etc.

Soapy water will have a good cleaning effect, but it should be noted that you should never use laundry detergent water, because laundry detergent is corrosive, while soap is alkaline and will not corrode the lampshade.

3. Polishing the yellowed headlights

Tips for cleaning yellowing headlights: spraying UV paint, polishing, fumigation and repair.

The headlights of the car are made of polycarbonate plastic, which makes the headlights more durable, but it also causes a potential danger of oxidation of build-up. When the sun shines on the headlights, the holes in the polycarbonate plastic on the surface of the headlights are enlarged, which accelerates the oxidation and yellowing of the headlights, and also causes dirt and debris to adhere to the outer surface of the headlights.

If the headlamp is yellow, you can spray UV paint, and you can dry it with an ultraviolet lamp, but this repair method is not recommended, because in addition to testing the master's craftsmanship, it will be easy to "**". Polishing can also be done, which is also relatively common and can be done by general car detailing shops. In addition, it can also be fumigated, first affixing a seal on the edge of the lamp, then sanding it one by one with sandpaper of different thicknesses, and finally using a professional tool to get the protective film on.

The role of car headlights

Car headlights are mainly used for night driving lighting, low beams are used for urban roads with street lights, and high beams are used for suburban roads such as no street lights or highways. Turn signals are the most commonly used signal lights and turn on when a vehicle needs to steer. It should be noted that the time to turn on the turn signal should be about 30 meters to 100 meters away from the turning intersection, not when it has already reached the intersection, so that the trailing vehicle is caught off guard and causes a rear-end collision.

When the brake light is on, it tells the vehicle behind that it is braking and pays attention to slow down. When you notice that the front taillights are on, be prepared to slow down. Emergency signal lights are used in emergency situations such as when a vehicle breaks down and needs to be temporarily stopped, and double flashing should also be turned on in bad weather with low visibility.

Emergency lights are closely related to driving safety, so check whether they are working properly from time to time.
