    Trailer Lights Question

    My new to me trailer has 5 wires going into a 4 flat plug. Every thing works but when the turn signals are on the opposite side blinks slightly. Is this a gounding issue? or something with the way I have it wired to my truck. Thanks for any help/advise.

    Sounds like ground to me. Your 5 wires probably includes one wire for each side of the tail/marker lights, with one being brown and one brown with a yellow stripe.

    Check your ground where the white wire attaches to the tongue, then check for ground lugs at the light fixtures themselves.

    I have 2 wires each side for the tail/marker lights..a brown and yellow, and a brown and green. What is the ground at the lights? This trailer does have drum surge brakes if that makes any difference.

    Some lights have a pigtail that goes to the frame near the light, and some ground internally to mounting screws inside the light.
