Comparing Amber Clearance Lights with 1-Wire vs. 2 Wires

Updated 01/18/2017 | Published 01/17/2017

Question:

I am looking for an oval amber clearance marker light with two bulbs and one wire. I have found item MC66AB which is the correct size but with 2 wires. Any help would be greatly appreciated. Thanks.

The difference between a clearance light with one wire and one with two is simply that the 1-wire type uses the light's mounting hardware to establish the ground, rather than a separate ground wire. The two are interchangeable so long as the mounting surface on the trailer will allow you to drill a hole to let you attach the white ground wire to the frame. Alternately, you could attach the ground wire to another of the existing ground wires on the trailer.
