1. The lamp of a car is as important as the eyes of a person. The headlamp not only plays a very important role in driving safety, but also is the focus of the car's beauty. However, what should I do if the lamp shell turns yellow after a long time? 2. First of all, we need to know the cause of yellowing. In many cases, it's caused by long-time exposure to the sun. The lamp shell has some chemical reactions under long-time exposure, which is similar to a layer of fog. This has a lot to do with the material of the headlight shell. And sometimes changing a high-power light bulb by yourself will cause the light shell to turn yellow. 3. It's easy to know the reason. A simple way is to use 2000 sandpaper to dip into water and polish the aging layer off. It should be noted that when grinding, attention should be paid to the strength. If the light is a little bit, it will not be worth the cost if the light shell is scratched. 4. Polish off and apply polishing agent again to ensure the effect. Finally, spray a layer of clear oil on the paint to protect it. 5. If it turns yellow seriously or wants to solve this problem in the next year or two, another way is to change the light housing. Now online shopping is very powerful, there is no one you can't buy, you can buy a light shell to replace it. However, it should be noted that it is necessary to melt the sealant for headlight assembly when changing the lamp shell, which requires the process. And online things are mixed, you must buy good things, or you will get yellow if you use them. 6. It should be noted that when parking, do not park in the sunny place, try to park in the shade. Wash the headlamp assembly surface when washing the car. In the process of driving, the car body will surely stick some dirt, and so will the headlights. Therefore, the surface of the headlights should be cleaned regularly with a soft cloth to prevent the dirt from sticking more tightly for a long time, which will make it more difficult to wash. Then wash with alkaline water. Alkaline water can be washed with soapy water every three months. After cleaning, remember to wipe the headlight with polishing agent, and then wax it
