This is about trailer lights as I try to get my trailer ready for the Michigan Jamboree of Ts and, frankly, I may have done a dumb thing, which is not unusual.

The lights on my trailer work. They are the round kind with two wires coming out of the back. I'm trying to install extra lights for safety. I disconnected the drivers side taillight -- the light with the license light -- to tap into those two wires for the new, extra lights. But now, although the original light lights, there is no function to the light: no turn signal, no brake light. It just lights. It's brighter on one wire than the other. Now, before I disconnected the wires from the existing light, it worked fine!

I freely admit I know nothing about wiring or electricity. I thought it would be a simple matter of tapping into the wires.

Any suggestions would be deeply appreciated. We're trying to leave Tuesday morning for the Jamboree so, as you can see, my time is limited.

Thanks in advance.

Marty One of the two wires in the original light is for the taillight. The other is for the brake and turn signal. If you tapped into BOTH wires the light you are trying to add will NOT work.
You need to tap into the wire that is for the taillight with one wire on your new light and GROUND the second wire on your NEW light. By ground I mean bolt or screw it to the metal frame of your trailer.
The original tight on your trailer might not have a separate ground wire on it, and is relying on the bolt that hold it to the trailer to ground it.
