[AT] Semi OT - Trailer question

[charlie hill]

My bet is a ground problem.  The lights are going to ground through the 
brake circuit.  Are the brakes wired through a seperate harness from the 
lights?  If so check the ground between the trailer and the tow vehicle.  If 
everything runs through a single connection like one of those round trailer 
plugs with a single ground wire then the problem is somewhere else.
