Car headlights usually become yellow and clouded after working for a few years. This cloudiness is a result of wear on the car headlights. The most common reason behind such cloudiness is oxidation resulting from the polycarbonate lens. Such cloudiness dims the light emitted from the headlamps, which may create problems when driving. Hence, car owners should try to sort out this problem in order to drive comfortably, as well as enhance the aesthetics of their cars.

Although the headlights can be resurfaced with the help of a mechanic or auto dealer, but you can do the job at home itself with a small effort. The things you would need usually are a clean cloth, detergent, water, headlight lens sealer, headlight lens polish and sandpaper.
