Question:

On the right side the lights fine, unless I attach the light unit to the trailer its self then the lights go very very dim.

Sounds like you have a weak grounding issue.

I would make sure that the ground wire or stud is secured tightly to a clean surface on the frame. If the wire is attached to the body or a surface with an undercoating or rust it can cause a ground problem. I recommend cleaning the area or finding a better grounding spot for the wire of light to be mount to.

I have linked our Help Article on wiring for your convenience, and if you continue to have issues I would be more than happy to further troubleshoot this with you.
