Question:

HI...I want to run a dedicated ground wire to all my boat trailer lights I am putting on but my new lights only have the 2 wires coming out of them. Where or how do I connect the ground wires? Thank you for your response.

Hello Derwin, thanks for reaching out. You can do that and ground all the lights to the frame. Typically the two-wire lights will have one wire for power and another for ground. The ground is typically a white wire, but the wire color can vary a bit depending on what light you are using. If you can tell me all the wire colors on your lights, I should be able to tell you what is what.

Hi Jesse....Curb side light has brown and green wires and the other side has brown and yellow wires.

@Derwin Those sound like combination taillights that ground thru the mounting hardware. Brown should be running lights, green would be right turn and yellow would be left turn.
