Features to know about

Reliable Rear Identification: Durable Incandescent Light Bar

When you need a dependable rear ID light setup that just works, this Optronics 16-3/4" identification light bar delivers. It uses three replaceable 194 incandescent bulbs under a red lens to provide bright, consistent illumination. Each light is part of a sealed, waterproof housing mounted to a strong white steel base, built to handle everyday use on the road. The P2-rated beam pattern gives clear visibility straight on, keeping your trailer compliant and easily seen from behind.

Built Tough for Everyday Use: Steel Base and Sealed Lights

Road grime, vibration, and weather can wear down weaker housings. This light bar’s durable steel construction and white powder-coat finish hold up over time, while the sealed lens units keep moisture out. Even though it’s an incandescent setup, it’s designed to last by protecting the bulbs from corrosion and water intrusion. The surface-mount design attaches securely with standard hardware for a solid fit that stays put mile after mile.

Simple Wiring That Works: 1-Wire Grounding System

No complicated wiring harness required here. The single-wire design connects directly to your running light circuit and grounds through the mounting hardware. That straightforward setup makes installation easy for DIYers who just want reliable lights without the hassle of rewiring. At 12.8V it draws only 1.0 amps total, so it won’t overload your system when tied into standard trailer lighting circuits.

Easy Maintenance When Needed: Replaceable Lenses and Bulbs

You don’t have to toss the whole bar if one light fails—each section can be serviced individually. The red lens snaps off by releasing two side clips, giving access to replace a bulb with part #A194B or swap a complete light assembly with part #MC11RB. Having easy replacement options means you’ll spend less time fixing lights and more time rolling safely down the road.

Exact replacementTheses were an exact replacement. Solved the problem, I painted the light to retard rust.
The metal is thin and the white paint doest appear to be enough protection. I sprayed it with Rustoleum I had in the garage.
Finish is much better and should last longer.



by:

Nice item, lights up beautifully (once I hooked it up properly), and a VERY REASONABLE price. Makes my "El Cheapo" trailer look like a million bucks (especially at night).

Great transaction. Wide selection, excellent pricing. All items were direct replacements and equal to OEM quality. Super fast delivery.
Highly recommend, only place I will buy trailer replacement parts.



by:

Advertised as exact replacement for Peterson PM 107-3, but it is not. The skirts on the Peterson light bar are 3/8", but the skirts on this are 3/16". Looks like a cheap foreign copy. The mounting holes are the same, which is a good thing.



by:

The light bar is a perfect replacement on my older model horse trailer. I appreciate the quality and fast shipping.



by:

Prompt, quality merchandise, how to videos to help with installation. We were very pleased with our purchase and highly recommend etrailer.com. Thank you!



by:

This replacement for my utility trailer was perfect. The exposure on the trailer means frequent replacement of the lens, but on occasion I need to replace the whole unit. This item is cost efficient, works just like the original and shipped instantly. The long wire left plenty for wiring. Very happy, etrailer always comes thru.



by:

Identical to the old one perfect match never thought I would find one for my horse trailer

by:

Etrailer has most everything that is needed for all trailer needs and more. They had an exact replacement marker light tor my Genisis Pontoon trailer.



by:

Excellent quality. Beautiful product. I bought this light to for my horse trailer. A lens on the existing light broke somehow. I did not even realize until I removed the original light that it was actually in horrible shape to begin with. When I received this new light, the size in dimensions were exact with the old one but it was so much better looking overall that i was actually glad that the original one broke! My trailer looks so much better now and for such a low price!!!
