What would cause the lights on my trailer to not work unless my headlights are turned on??? Nothing works unless my lights are on... it was like this when I bought it and I could retrace everything but hopefully someone will have a solution... thanks for the help...

MAKE SURE YOU HAVE A GOOD GROUND FROM TRUCK TO THE TRAILOR.

Funny as that sounds,starting last week it's the law here to drive with at least daytime driving lights.If your vehicile is older you have to turn your lights on.Captain Ahab said:
They make little light testers that can plug right into your socket that will tell if it's wired correctly.

Most likely a bad ground.
On some wooden trailers(probably some metal ones to)they individually have to run a wire from each light to a ground.

Agreed.
95% of trailer lighting problems can be traced to a poor/bad ground. Running individual ground wires to each light is a foolproof way of making sure.
