The plastic used in the headlight lens covers becomes brown with exposure to the sun. This is a dangerous problem and the only remedy that I have found is to purchase new headlight assemblies for about $200 each. This is unacceptable since the problem is due to the improper selection by the auto manufacturer of the correct polymer used to create the lenses.

I own a 1999 Jeep Grand Cherokee. The plastic covers on the headlights are getting so distorted that its getting hard to see at night. I have tried everything I could to clean them, but nothing works. Its starting to become a safety problem.

The headlight lens fogged, creating a safety hazard because there was reduced visibility of 50% at night. The fog in the plasticity in the lens itself. Has not been to a dealer, no repairs have been made. Called Chrysler, and it was out of warranty, and they would not replace the lens.

I own a 1999 Jeep Grand Cherokee. The headlight lenses have turned opaque (about 15% reduction in light transmission, using a standard photographic light meter). I have tried to polish this opacity "off" the lenses, using standard consumer plastic polishes, but the problem seems to be in the plastic itself and not a surface defect. I contacted Chrysler (1-800-992-1997) and talked to "[xxx], employee #6cm. I was informed that Chrysler considered this a "maintenance" problem. I consider the fact that approximately 15% of the light energy produced by the head light bulbs is not making it's way onto the road surface when I use my headlights, a safety mater, and request that you look into this problem.

Headlight lens have deteriorated so severely over a 3 year period that seeing at night is significantly reduced. Tried cleaning lens, but did not work. This is a severe safety factor.
