We tried going on our first camping trip of the season this past weekend.  We were checking the lights and when the headlights of the tow vehicle were off, everything was fine.  When the headlights were turned on, the lights on the trailer dimmed and the turn signals switched, right turn signal on tow vehicle with a left turn signal on the trailer, and the same thing with a left turn signal on the tow vehicle.  What could be the problem?

 First check ground. Are you using 4 wire or 7. 4 is easier, but lets see what your using first.
