How Long Can Headlight Restoration Last?
2 Answers
Headlight restoration can last for two to three years. Here is the relevant information: 1. Headlight composition: The headlight cover is injection-molded from polycarbonate or polymethyl methacrylate plastic. Whether it's halogen, xenon, or LED lights, they all generate a significant amount of heat when illuminated. This heat accelerates the aging of the plastic, causing the cover to lose its clarity and transparency, even turning dull and yellow, which directly affects the lighting effect. 2. Causes of headlight wear: Car headlights are a crucial component. After prolonged use, you may notice that the light emitted becomes dim and yellow, with reduced brightness, especially in halogen headlights, where this is more pronounced. There are two main reasons for the decrease in light brightness: first, external factors like windblown sand and gravel leave scratches and dust on the cover; second, the heat generated by the bulb inside causes the plastic cover to age and turn yellow.
I had my headlights refurbished last year, and now after a year and a half, they still look as good as new. The key is paying attention to regular maintenance. Every time I wash the car, I specifically ask the technician not to use strong chemical sprays directly on the headlights, and I try to park in a garage to avoid exposure to sun and rain. However, during my last self-driving trip to Qinghai, I drove thousands of kilometers, and a small stone hit the headlight, leaving a tiny dent, and the area has started to yellow slightly. Overall, how long the refurbishment effect lasts depends on the driving environment and how diligently you maintain them. With regular inspection and cleaning of surface dirt like I do, maintaining them for two years shouldn’t be a problem.
