My headlight lens covers appear to be scratched on the inside-but I assume this is moisture? Can the lens cover be removed or do you have to remove the entire light?

 

An adhesive and tabs hold the clear plastic lens on the headlights . You have to bake the headlight to remove the clear lens hopefully you don't break a tab, or worse. Then hopefully you get it water tight when you rebake it , and put the lens back on.

 

I found "grazing" inside my headlights. It's hard to get that out without sanding and polishing BTW.
