OK, so I replaced the trailer lights because one was all cracked up. I figured I'd replace both so they match - and they are only 12 bucks apiece. So, snip the wires, remove old lights. Rewire and check - and no @#$%^ lights. They don't work and I can't figure out why? Gotta be something I'm just not thinking of right?? I mean, the damn things worked right before I swapped for the new ones. Ground wire is grounded, wires are connected to where they are supposed to be... Any thoughts?
