Headlight lenses, even among the most luxurious cars such as Mercedes Benz, are as susceptible to debris and UV degradation as the body paint, perhaps even worse. For example, a Mercedes Benz Headlight Lens is made of polycarbonate plastic in order to make them impact resistant. This plastic is functional, but it can cloud over time as a result of UV exposure. As the lens gets blurred, it restricts the amount of light that can pass through the lens causing reduced visibility.

A dirty, yellowed, cloudy and otherwise dim set of headlights is one of the most common problems. Unlike a burned out bulb, yellowing headlight lenses make a C230 or SL60′s lights dimmer slowly over time. Because of this, they easier to ignore. The limited field of vision, however, can pose dangers for the driver and his/her passengers.

The customer told me that the dealership wanted almost $800.00 to replace the passenger side lenses. I was happy to save her so much money!
