This 2" round Peterson LumenX LED light puts out a solid, even red glow that’s hard to miss. The LumenX optics fill the entire lens with light instead of just a hotspot, giving your trailer a sharp, clean look and better visibility on the road. With five red LEDs inside, it’s more efficient than old-school bulbs and lasts up to 50 times longer. There are no filaments to break or bulbs to replace—just dependable light that runs on 9V–32V DC and stays consistent thanks to its regulated design.
If you deal with wet roads or launch ramps, this light is ready for it. The housing and lens are sealed as one waterproof unit, keeping moisture out even when fully submerged. That means no fogging, no corrosion, and no shorting out after a dunk in the water. It’s a set-it-and-forget-it solution for trailers that see all kinds of weather.
With its PC rating, this light pulls double duty. When properly mounted, it functions as both a clearance light and a side marker light without needing a specific top orientation to meet DOT requirements. That wider beam spread helps other drivers see your trailer from different angles, improving safety day or night.
Installing this one is simple. It surface mounts using the built-in black flange, and the distance between the mounting holes is 2-5/8" center to center. The standard AMP-style sealed plug connection (pigtail sold separately) makes wiring secure and weathertight. With an overall diameter of 2-15/16" and depth of 1-1/2", it fits neatly without extra adapters or drilling.
You don’t have to second-guess whether it meets legal lighting requirements—it’s DOT compliant and meets FMVSS 108 standards for automotive lighting. That means you’re covered for visibility, brightness, and safety wherever you haul.

Hi, everyone. Steven here with etrailer.com. Let's take a look at our Peterson LumenX LED clearance and side marker. It's a trailer light that is submersible with a round red lens. That's right, folks, so this round trailer light functions as both a clearance and side marker, depending on how you have it mounted when it's properly mounted. It does not require top mount position to meet DOT requirements for PC rating.
It's been sealed, it's waterproof housing and lens unit, meaning that you can put it in the water if you need be. As you can see, you're just getting the light, the housing and everything, there is no plug included. It does accept an AMP-style plug with pigtails sold separately, and that part number if you need it is 417-48, and that gives you a watertight connection. Now I have one here just for demonstration purposes today. It is not included.
As you can see, it has that rubber plug there, and then it just simply plugs right into the back, and that's gonna give you a nice, tight watertight finish fitting. And if I power on here, now you can see the red light. LEDs make great replacement for incandescent bulbs. They're bright, brilliant. The LumenX optics create a solid panel of light that illuminates the entire lens, so that makes it a lot better than some of the standard ones that are out there.
LEDs burn 50 times longer than incandescent lamps, so they're gonna be better for longevity and just brighter and overall more visible. DOT compliant, as I mentioned. It does meet all FMVSS 108 requirements as well for automotive lighting. I'm gonna go ahead and turn back on the overhead lights for you real quick. Now getting a closer look here as I shut this off, again, no pigtail included, but I do wanna show you what it would look like when it's installed on there.
So again, this part number is 417-48, sold separately. The light itself is about 2 15/16" diameter overall, and about 1 1/2 inches deep. And you have three mounting holes. The distance on center of those mounting holes is 2 5/8 inches. Well, folks, I think that's gonna wrap it up for our quick look together. I'm Steven, thanks for watching, and as always, stay safe while you're towing.
