Situation: The passenger side reverse light isn't working while the drivers side is, so I suspect there's a short somewhere on the passenger side, and I was going to try a new socket to see if it clears up the problem. The issue I'm having is, I can't find any reliable information on what the appropriate socket is, or whether I'll have to try to get an OEM one. If anybody could help me find the correct part, I'd greatly appreciate it!

Thanks.

 

From experience so far, local parts stores have GM and maybe Ford sockets. They will fit, but not without modification. Haven't had much luck online either.
Get a test light, or make one with one if you have a spare (known good any size) socket
