Do you have power going to the sockets?

Could be the switch, but you need to check for power and look at wiring before jumping to that conclusion. Have you tried turning the lights on and off a few times? Sometimes when a switch is going bad, if you play with it the lights may or may not work.

I have heard that trailer wiring can affect light operation.

I would check out the connections in back (left side at frame rail) that go to the trailer connector.. If a crappy job was done all sorts of bad things can happen..
