headlight lenses getting dull and cloudy
 

The headlight lenses that cover the xenons - i assume they're clear plastic - have gotten dull and cloudy over the years. Is there a product that can make them crystal clear again?

try and check out this weblink. maybe it will help. you can call their 800 number as well M-Sat. http://www.properautocare.com/rescsphainpl.html

i use a little clay bar to clean it off and some lemon pledge to bring back the gloss.

Meguires (spell check anyone) has a lens cleaner that works pretty well depending on how bad the lens is, called PlastiX, like $5

If the vehicle is still under warranty
they will be replaced free under that warranty
