When your trailer sees rain or even full submersion, you need lights that hold up. This Peterson light is built as a sealed, waterproof unit with the lens welded directly to the housing to keep moisture out. The entire circuit stays protected, so water won’t reach the bulbs or wiring. That makes it a dependable choice for trailers that often deal with wet roads or launch ramps.
Seeing and being seen is what matters most on the road. This PC-rated light spreads its beam 90 degrees to either side for a full 180 degrees of coverage. When properly mounted, that wide pattern lets it serve as both a clearance and side marker light—bright enough to be seen from the front, side, or rear to help keep your trailer visible in all directions.
This light uses two long-lasting incandescent bulbs rated for over 15,000 hours of use. They run on any 12V DC system and produce a consistent glow through the red lens. It’s traditional lighting that’s still tough and reliable, designed for consistent brightness over years of use.
Mounting this light is straightforward. It surface mounts using bracket B154-11 (sold separately) and connects easily with a standard 2-wire female plug (153-49, sold separately). The male pins make for a solid connection that’s quick to attach or replace without complex wiring or adapters.
At just 3-13/16" long, 1-1/4" wide, and 7/8" deep, this rectangular light fits cleanly on most trailer surfaces without sticking out. It meets DOT requirements for clearance and side marker applications, so you know it’s road legal and ready for daily use.

Today we're taking a look at the Peterson red trailer clearance light. Now this red light functions as a clearance light for your trailer. It's sealed, so it's protected from dust and moisture. Internally it contains two incandescent bulbs, one on this side and one on this side. Now your base and wiring are not included. This is designed to snap into a base.
Something that would be very similar to this right here, just a bracket that has the ports for it, has the grounding function through the mounting hardware. And then a single wire designed for power. But again, your base wiring and hardware, all those items are sold separately.It is Department of Transportation compliant, has a nice red lens on it with a white base. When it comes to the dimensions of the unit, we took a measurement edge to edge and got a measurement of about 3 and 13/16 inches long by and inch and a quarter. And a depth of just that lens area measures about 7/8 of an inch deep.I'm going to go and hook up some wires to it that way you can see what it looks like with power running to it and then we'll also turn off our overhead light so you can see it in a low light setting.
So you can see here, it sends out a really nice consistent signal, pretty bright design, two bulb design and those are incandescent bulbs. But it allows for a really nice signal output.That's going to do it for today's look at the Peterson red trailer clearance light.

Excellent product, quick shipping!!!
lights work great. Pop right in and out. I keep spare lights when traveling.
They worked out great, installed all 5 of them on our 1994 Pace Arrow motorhome. Saved the old ones that still work for back up. Only one had a bulb burnt out and another the red plastic had a hole in it but the internal bulbs were still working.
They were a great price so we decided to replace them all while we were ordering.
Item arrived as described, timely shipping and convenient updates along the way.
Will be buying from etrailer down the line when another need arises.
Highly recommend.
I needed to replace some old side marker lights on my enclosed motorcycle trailer but wasn't sure which ones would fit. After contacting etrailer, I got an immediate response from Steven C., with photos and info on two separate lights - one LED and one regular bulb. They arrived a couple days later and fit perfect! I have used etrailer many times over the years and they are always prompt, cheerful and very helpful!
This is more of an overall review of all of the lights I purchased for my 9 year old trailer - The lights had completely broken or rusted off, so we obviously needed new ones!
The fact that the pictures reflect exactly what the product looks like AND includes the cord in the picture is VERY IMPORTANT TO ME! THANK YOU!!
You provided enough information about the product and products it can replace for me to confirm what I needed to fix the trailer!
I received a prompt email that one of the parts was backordered, and the tracking information was fantastic.
Great job helping select the correct lights. They fit my trailer perfect.
Communication and correct part! Top notch experience. Thank you etrailer!
My order was received packaged and shipped in a timely manner! Trailer side markers were exactly what I needed!
Everything was great and shipped quickly. In fact, I just put together another small order to etrailer for more parts.
Just what I needed!
Great and professional service, quick expedited shipping on order, exactly what I needed, plug and play trailer replacement lights. Will continue to do business with Etrailers and Etrailer ONLY! I HIGHLY reccomend to anyone seeking or in need of trailer items.
Excellent customer service! Product exactly as described, installation was a breeze thanks to the information provided on the etrailer website.
I'll definitely do business here again and would recommend them without hesitation.

PS-I'll snap some pictures and post them once it quits raining here.
The shipping was quick and in-expensive. Lights are great.
Just what I needed. Very timely. 3 days. Thanks for the very thorough responses.
They had what I wanted. I ordered it and got it within a reasonable time. In addition, any business that has people so willing to help as Sarah S. gets an extra star from me. Customer service builds customer support. If you want loyal customers hire more people like Sarah S. Good luck to you all.
