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.Google+

Mercedes-Benz E320 Head Light Lenses Become Cloudy/Opaque Due To Sun Exposure
Mercedes-Benz E320 Problem
You no longer have to replace the lenses. There is a kit put out by Mcquires which includes a selection of sanding discs and applicator for a drill. You physically remove ALL the garbage from the lens and then polish to a brilliant finish. The lens looks brandy new once again and it's not a temporary fix like the polish type "miracle" cleaners.
