Running Lights don't work
We have a travel trailer with & a brake controller in our car. The brake lights and the turn signals work on the trailer, but NOT the running lights - what could be wrong?

I had a similar problem recently. Turned out that the new receptacle in the truck bed (for a 5er) was not mounted securely to the bed wall, so the umbilical cord would not make a good connection. Once I tightened everything up the lights worked fine. You can do a search in some of the other categories and come up with other suggestions for troubleshooting.
