Installing LED Clearance Lights With 2 Wires
Question:
The led marker lights I just bought have 1 red wire and 1 black wire. How would these hook to standard trailer wiring?

Expert Reply:
Two-wire LED clearance lights such as the Red # MCL32RB or the Amber # MCL44AB have one wire for the power lead and one ground wire. The wire that was attached to your old clearance lights will be spliced to the power wire of your new lights. The black is power and white is ground for these lights.
If you take a look at the video I have linked you can see how these lights are installed. I have also attached a couple of links to help articles on trailer wiring which you should find useful.
