Today, we'll be installing the Peterson Trailer Light, part number 431800. We'll begin by removing the two nuts at the back of the light. With that done, we'll slide the light into position, making sure the two bolts and wires go through the proper holes. We'll then reattach the nuts and tighten them down. Now, we can splice our wires together. We'll strip back the black wire from our turn signal.
We'll splice the black and brown wires together and add a butt connector the red wire. We'll cut off our excess 4-pole wire, split them apart, and strip the green and brown wires back. We'll connect the brown wire from the 4-pole to the brown wire and black wires from the lights. Then we'll connect our green wire to the red wire. Once that is done, we'll tape up the connections and our install will be complete.
There you have it for part number 431800, the Peterson Trailer Light.

Thanks etrailer !! I couldn't find lights for my 10 yr old trailer anywhere locally due to a specific size. Etrailer had exactly what I needed plus I received them in about 3 days. Definitely recommended. Just ordered tires too for a lot less than a local store. 16131

After shopping carefully, I chose the Peterson Trailer Round Tail light because it was 3 3/4 inches wide, perfect for my 4' x 6' utility trailer. The lens cap has two retaining screws which prevent easy losses when accidentally bumped. The wires exit the rear surrounded in molded soft plastic, otherwise an easy target for fraying wires. I was suitably impressed with the durability of the light that I have now installed a set on my 16' flat bed trailer. From experience, bigger lights attract more damaging bumps. 14095
