Due to exposure to the sun, lenses for head lights may become opaque (cloudy or hazy). This reduces the effectiveness of the lights. Our technicians tell us plastic polishes can improve the clarity of the lenses, but replacement of the lamp housings is the only way to regain the full intensity of the lights.

I just replaced the housing, easily found on eBay.
My head light lenses have become opaque. I saw a commercial that described how to "buff them out" with a cream. Has anyone tried that?
