Trailer Lights Issue

I bought an adapter from Menards I believe and it works fine. Do you keep getting the same brand when you get a new adapter?

It's obviously a wiring issue on the trailer and not the adapter. If it works on one trailer it should work on the other.

Either the wiring, or quite possibly a bulb. I've had some strange stuff happen with my boat trailer lights/signals that a bulb replacement somewhere takes care of the problem.

Go to Amazon.com and type in "Hopkins 47385 Multi-Tow Adapter". That gizzmo works with both 4-pin and 5-pin connectors. I leave it plugged into my 2010 Tahoe at all times.
