I guess I missed some of the postings since I was in Alaska,,,,,,,, these are the 3 inch lights at the top..rear, they are sealed so you can not replace the bulbs. I contacted PC they sent me the mfers name Command,,, ordered two,, easy to replace,, just cut the new plugs off the black/white wire retwist into the wire nut, a little bit of caulk and done,, I think they were 8/9 bucks each,,, shipping was not cheap figures,
