Square Trailer Clearance and Side Marker Light with Reflex Reflector - Amber

This square light can be used as a clearance light or side marker light with side reflex. This PC-rated light functions as both a marker and clearance light when mounted properly at a 45 degree angle. This amber lens is reflectorized, meaning that a separate reflector is not needed for DOT compliance. The light measures 2-7/8" long x 2-1/8" wide x 15/16" deep. The light features a replaceable, screw-down lens and easy-to-replace bulb. The light contains a single lead wire for power and is grounded through the mounting stud.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MC37AB Review

Today we have Optronics Square Trailer Clearance Light, part number MC37AB. This light features a reflectorized lens that is DOT compliant. Both the lens and the bulb are replaceable, to make sure this light will last. It is a single wire system, meaning the wire lead that we have will be for your power source and the mounting stud on the back will double as our electrical ground. Next, we will grab our power supply and test the light. We will take our ground connection and clip it to the stud and we will take our power source and clip it to our wire lead. Next we will turn off our overhead light, to show you how bright the light is. And there you have it, Optronics Square Trailer Clearance Light, part number MC37AB.

works, easy to install. Case is all amber plastic even in the back and does not appear to be as rugged as I would like but hopefully it will stand up to the abuse. 460531

Great looking tire. Bought a used trailer. Guy said tires were "new" but date code says they are not. Both had cracking & were made in 2010. These new tires were both made a month or so ago from ordering. Practically direct from factory they are so new. Look good and bolted right on. No issues. Much more confident that I've reduced the chance of a blow out. 433627
