'89 F250 Headlight Lens
 

Alrighty....I was upgrading my headlights and noticed a few things. First, one of the sockets where the bulb goes in is melted. Second, the flat lenses are coming apart from the reflectors. Third, one of the reflectors has no mirror finish anymore.

So, my questions are.....
1) How to remove the reflector assemblies?
2) Are the lenses supposed to come off?
3) Do replacement parts come as one unit or are they supposed to be glued and sealed together by the user?

The bright side is I guess I can polish the inside of the lenses now as opposed to just the outside! :-X06
