Plastic headlight restoration is the act of refinishing aged headlight lenses that have succumbed to headlamp oxidation and other environmental hazards of travel, weather, and exposure to caustic chemicals. This condition which results in cloudy lenses is known for causing reduced night time visibility for travelers as the condition becomes worse. Because cloudy headlights can be restored to a like new condition, it is much more economical to restore the headlight lens, rather than replace the lens. There is an increasing number of professional headlight restoration services that charge approximately $60 to $125 to restore both headlights on a vehicle. Replacing the lens can be much more expensive. For example, some brand new headlight lens assemblies can cost over $250 each (plus the labor to replace the lens). There are many do it yourself headlight restoration kits available on the market, however, most of the kits do not restore the headlights nearly as well as an expert headlight restoration service. The main reason for this is because most of the do it yourself kits do not include the proper tools or techniques needed for professional results. Furthermore, some professional headlight restoration shops are applying a urethane or acrylic clear coat to help protect the plastic lens from UV exposure after the headlight lens is restored.
