No Running Lights & Weak Signals on Trailer When Installing New Lights

Question:

I just installed a new set of led tail lights on my 2013 Jayco Jayflight 22FB. The trailer on the left side has 4 wires 2 green, one red, one black , the left side has the same except only 1 green. The led light is a two section light and has has 80 diodes, 40 on each side of the single light My running lights do not work at all and when I turn on the head lights of my truck the turn signals and brake lights are really weak What do I do?

This is definitely a case of a bad ground. So what I would do is try grounding the # DG52720PB lights you have directly to the trailer frame using a ring terminal and self-tapping screw. Make sure the frame is bare metal and clean, without any dirt, paint, etc.
