My 04TL is showing signs of UV ray attack as headlight surfaces are extremely easy to scratch and have internal cracks or fractures. I live in west Canada and I am sure that they will crack up come winter and have to replaced. Any one else have this problem?

 

I haven't seen any 3rd gen TL's with that problem yet. I am very paranoid about that so i wax my headlights and I try to keep the front of my TL in the shade while I am at work.
