What causes oxidation in the first place

Yellowing of the headlamps is a relatively new issue that did not exist when they were made of glass. Carmakers began using plastic to produce headlights in the 1990s to reduce production cost of headlight lenses. Now, modern cars’ headlights are made from Polycarbonate plastic, which is durable, cost effective, but yet fragile. Because the Polycarbonate plastic headlights are susceptible to UV rays, car manufacturers added a thin protective film that shields the headlight lenses against sunlight, UV ray, pollution, and more. 

However, the protective coating can only last for a while and usually deteriorate due to wear and tear. When this happens, the bear headlight lens becomes vulnerable. It’s only a matter of time before the lense starts to discolor and get foggy due to oxidation. When the film has faded completely, the sun’s UV rays hit the brittle material of the headlights, oxidize it, and before you know it, the headlights have turned yellow.
