How Long Can Headlights Last After Restoration?
1 Answers
Headlight restoration can last for two to three years. Here is relevant information about automotive headlights: 1. Headlight Covers: They are injection-molded from polycarbonate or polymethyl methacrylate plastic. Whether it's halogen lamps, xenon lamps, or LED lights, they generate a significant amount of heat when illuminated. This heat accelerates the aging of the plastic, causing the covers to lose clarity and transparency, or even turn dim and yellow, directly affecting the lighting performance. 2. Causes of Reduced Headlight Brightness: One reason is scratches and dust left by external debris like sand and gravel on the covers. The other is the heat generated by the bulbs, which causes the plastic covers to age and turn yellow. 3. Headlight Restoration: Traditional restoration involves sanding and polishing the headlight covers, followed by techniques like waxing and coating to restore their brightness and transparency.
