Vinyl wraps are intended to either reduce the light output of a vehicle's headlamps or simply change their appearance in the case of headlight tint. Covers were originally devised for wartime use in coastal cities in the US and were made from steel, tin and aluminum with downward facing grates to limit light during blackouts and brownouts. In addition, to these types of covers thermoplastic, urethane films generally applied to the painted surfaces of a new or used car in order to protect the paint from stone chips, bug hits, minor abrasions and UV damage. It does not affect appearance or aerodynamics, being virtually invisible from just a few feet away and with minimal maintenance the film will last many years, keeping your paint protected while looking great. The film is also used on airplanes, RV's, cell phones, electronics, screens, motorcycles and in a growing number of applications.
