I can't remember if the two outer tail lights have the same rubber backing like the inner/reverse does.

Or do they come like this? To where the inner tail lights only have the rubber backing?

All 4 of mine have a seal of some sort.

 

That's what I thought too. I remember the outer ones have the black rubber backing too. But then I doubt myself by looking at this EBAY posting.
