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.

Trailer Side Marker Lights received fully met my expectations.

Ordering process was streamlined through the eTrailer.com website.

Response time on order and shipping was outstanding.

eTrailer is a great company for the consumer!!!



by:

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.



by:

Average quality by today's standards but price couldn't be beat.
I have an old trailer and this type of light seems to be very rare with the stud and wire so I was happy to find this replacement.



by:

Light was exact match to what on the trailer other then mounting bolt was slightly smaller but did not effect the install. Just took a few minutes to replace broken light.



by:

Exactly what I ordered, easy installation, works perfectly . . . will definitely purchase from here again the next time I need to replace one of my trailer lights.



by:

Purchased 2 of these that were exact replacements for lights that had been damaged or destroyed. Installed both in about 10 minutes with ease. Self grounding attachment stud was a real plus. Product was high quality and service was excellent. I have ordered several items in the past from etrailer and shipments were very fast and the people are great to work with.



by:

The trailer lights were shipped and delivered in a reasonable time and the price paid was very good. I appreciate the timely communications that kept me updated on the status of the order.



by:

Side marker lights were just what I wanted and were delivered in 3 working days. Thanks!



by:

I think you had and delivered exactly what I was looking for.Thanks for the speedy delivery.



by:

This is a great product it took me less than 10 minutes to install 2 of these lights, entrails customer service is second to none thank you etrailor



by:

Just as described. Very convenient having a reflector/side marker in one piece.



by:

Very very slow to solve my issue!!!

by:

The lights were of great quality and the perfect match for other lights on the trailer.

  • How to Remove Side Clearance Light with Nut That is Fixed to Threads on Bolt
    Since the nut on the back of your Square Trailer Clearance and Side Marker Light with Reflex Reflector # MC37AB is seized to the bolt I recommend removing the face of the light (the two screws at the front) so you can then secure the bolt on the inside while you loosen up the nut at the back. You shouldn't have to go through this process when you install the new lights though.

  • Replacement Square Trailer Fender Clearance Light
    We offer tons of lights like the Peterson Piranha LED Clearance or Side Marker Light w/ Reflector # M170A which measures 3 1/8" long, 2" tall, and 15/16" deep; or the Square Trailer Clearance and Side Marker Light with Reflex Reflector # MC37AB which measures 2 7/8" long, 2 1/8" wide, and 15/16" deep, that may fit your needs. But, without measurements and some reference pictures it will be difficult to gauge what exactly you need.
