Outside light lenses for my 2005 Bounder
My recently acquired 2005 Bounder is missing a lens on one of the perimeter lights (the little red lights that go around the top, outside) and a couple of others are cracked. I'd like to replace them, just the lenses if possible, but I don't know where to find them. They must be some sort of standard part, but when looking on Amazon they all look kind of alike, and they would rather sell me the whole light assembly anyway.
Where do you look for this sort of stuff, and how do you describe exactly what you need? 2005 Bounder doesn't mean much to most outlets, it seems.
