What Causes the Peeling of Car Headlights?
2 Answers
The reason for the peeling of car headlights is: After picking up the car, the original headlight film was not removed. Although it sticks to the headlight cover, over time, peeling will occur. Car headlights, also known as car front lights or car LED daytime running lights, serve as the eyes of the car. They not only relate to the external image of the car owner but are also closely linked to safe driving at night or under bad weather conditions. Steps to remove the headlight film: 1. Use a fingernail or a hard card like a bank card to lift one corner of the headlight film; 2. Slowly peel off the film; 3. After the film is removed, some adhesive residue may remain on the surface, which can be removed using alcohol or a heat glue method, followed by rinsing with tap water.
Oh, I have some experience with this issue. My car has been in use for several years, and the headlights started peeling too. At first, I thought it was just dirt, but later I realized it was due to aging. The main reason is that the plastic lens covers are exposed to sunlight for long periods, and UV radiation makes the material brittle and prone to cracking—just like sunburn on skin. Additionally, road debris like flying stones and scratches can accelerate the peeling. Sometimes, using improper cleaning agents, such as regular glass cleaners containing harsh chemicals, can corrode the lens surface. I recommend applying a specialized headlight protectant regularly to slow down the aging process. Cold winter temperatures also make the plastic more brittle, so extra care is needed. Now, I’ve replaced my headlight covers and clean them weekly with a damp cloth, avoiding direct sunlight exposure—it’s working well. In short, peeling headlight covers not only affect appearance but can also reduce nighttime visibility, compromising safety, so it’s best to address it early.
