Hi its as if the running lights are bleeding into the turn signal circuits, what kind of plug are you using ex: 7way, 6way, 4way, do you have a test light, or volt meter?

thanks, ***** ***** thing I would do is disconnect the trailer, and check the plug at the back of the tow vehicle..................then I would take a test wire, and energize the lights thru the plug on the trailer to make sure that the circuits are not crossed, and to identify the locations of each circuit on the plug making a diagram as I go. I would also remove the tow plug, and disassemble to make sure all wires are atatched properly , and freys of wire are not crossing onto other pins
