Running Lights Not Working

Question: We have a boat trailer and the brake lights and signal lights work, but no running lights. Hooked it up to two different vehicles with same issue. Where do I start to look for the issue?

Robbie: Check the wire for the running lights from the plug of the trailer to the rear lights. Hook the trailer up to the tow Vehicle and using a 12V test light find the running light wire at the plug and follow it back to the tail lights.
