Video Transcript for Optronics Trailer Lights - Clearance Lights - MC42AB Review

Today we are going to show you Optronics Double Bulls-Eye Trailer Clearance Light, part number MC42AB. This light features dual bulbs for high light output. It is designed to surface mount, using mounting holes that are 3 inches on center. These mounting holes will also double as our electrical ground. Both the bulbs and the lens are user replaceable and there is a single wire lead for your power connection. You will use hardware like a screw or a bolt to complete your electrical ground and mount the light and the lens snaps back into place. Next we will hook up the light to a power source, so you can see how it works. We will connect our ground to the mounting hardware that we ped inside the light, and we will connect our power to the wire lead. Next we will turn off the overhead lights so you can see how bright the light is. And that is Optronics Double Bulls-Eye Trailer Clearance Side Marker Light, part number MC42AB.

Trailer Clearance Lights #MC42RB, easily installed, nice lights. There could be a little more space (maybe 1/8" in depth) on the backside so the wire could be positioned through an existing hole in the trailer and the light assy would sit completely flat against the trailer. Seems to be good value for the money and they are cheap. 355579
