Features to know about

Reliable Visibility with a Classic Look: Amber Incandescent Clearance Light

This rectangular 3-3/4" x 2-1/4" amber light gives you dependable visibility as a clearance or side marker light. It uses a premium 194 incandescent bulb that delivers up to 15,000 hours of light and draws just 0.25 amps at 12V. The P2 rating means it shines a 45-degree beam on either side of its centerline for clear, direct illumination that meets DOT standards. It’s a simple, proven design that just works when you need it.

Built to Last: Durable Chrome-Plated ABS Housing

The chrome-plated ABS housing doesn’t just look good—it holds up well against regular road use. The sturdy build stands up to vibration and general wear, keeping the lens and socket protected. It’s a solid choice when you want something that looks clean and holds up over time without needing constant replacement or touch-ups.

Straightforward Installation: Flush Mount with Twist-In Socket

Mounting this light is easy thanks to the flush design and included stainless steel screws. You’ll just need a 1-1/4" diameter socket hole for the wires and socket to pass through. The twist-in socket has both the lead and ground wire built in, so wiring is simple and secure. With a center-to-center mounting hole spacing of 2-11/16", it fits neatly in place without guesswork.

Simple Maintenance: Standard Bulb and Direct Replacement Compatibility

When it’s time to swap bulbs, you can use a common 193 or 194 type—no hunting for hard-to-find parts. This light also serves as an exact replacement for Truck Lite #1571A, Optronics #MC71AB, and Grote #47053, making it easy to match with existing setups or replace older housings directly.

Good quality, differences in the design require modification to replace vintage fixture.

The lens is no longer removable separately from the mounting screws. There is no rubber seal behind the housing anymore either. This means the fixture is no longer water tight when mounted in place of the original Peterson marker lights of this style. Additionally these no longer ground through the fixture and require adding a ground if not already set up with a two wire system.

These do upgrade to a 193/194 bulb and fit the classic aesthetic of the original Peterson markers. Sadly they require a decent amount of modification to the vehicle to make them mount and work. Also, the screws are cheese grade, I used some stainless self drilling/tapping #6 screws. I also glued the fixtures to the vehicle with Sika-Flex. I'm hoping when the time comes I can remove just the lens and replace the bulb.

Sorry to hear they weren't quite what you were hoping for, Sean. Hopefully it will get the job done though. What did you install this on?

by:
They look just like the picture
by:
Couldn't find these parts from the manufacturer of the trailer or the dealer. E Trailer had them in stock.
by:
Fit and worked as expected

I purchased this item to replace an older style Peterson 126 light in a 1996 horse trailer. It took a few minutes to make the new fixture fit. It was easy to do and works great! Once installed it looks like the original one it replaced.
The new 126A light was just slightly different from the old model that it replaced. The old light was connected using a single wire, the mounting screws were in a different location, and the center portion was slightly smaller in diameter.
Using a round file I enlarged the hole in the trailer slightly, drilled two new mounting holes using the light fixture as a template, and installed a ring terminal on one of the wires to connect it to the trailer (ground). Perfectly happy with the results.
by:
The whole process was seamless. Very friendly customer service. Shipment was quick and parts came as ordered. Would recommend to anyone needing trailer parts/accessories!
by:
Used as replacement on our 1996 Circle J horse trailer. I ordered the identical Peterson light that was on the trailer from the factory hoping for a simple swap. These lights seemed to have been redesigned. The originals on the trailer had separate mounting holes so I ended up having to modify each light to mount using the existing holes. I also had to make the center hole for the fixture larger on the trailer. Not a deal breaker but ended up taking a lot longer than I was anticipating.
by:
I FINALLY FOUND THESE ! These items They aren't readily available in amber and I had to browse a lot of web sites to find these. That being said, they will do the job but are made of a cheap plastic .I hope they won't crack I like them because I don't have a lot of clearance and these don't extend out (SLIGHTLY RECESSED) which is why I bought them.
by:
Perfect. Just what I needed. May order some more later. Thx
by:
Love my etrailer lights that I purchased last year. Perfect fit and match on my 1981 Bluebird Wanderlodge
by:
Dimensions were slightly off from existing parts... but I have 1993 horse trailer so it was not a surprise. I was able to redrill screw and socket holes and install without much fuss.
by:
One year later the trailer lights are still working like new.

Just what I needed to match the existing lights on my trailer, and the price was right.
by:
Exactly what I needed for my motorhome
by:
Good replacement match.
by:
I rated these as a 3 star because at some point they must have changed the design so they are the same part number as my old ones but the sockets is much bigger. As for quality and look I would rate a 5 star, especially if they had worked!
