Traditional bulbs can fade or burn out fast, but this Peterson LumenX LED light keeps shining. The red LEDs last up to 50 times longer than incandescents and draw less power from your 12V system. Its regulated design keeps the output steady and prevents overheating, so you get a bright, clean light every time without worrying about brittle filaments or bulb changes.
Water intrusion is a major cause of light failure, but this one-piece LED housing and lens are completely sealed. It’s waterproof and submersible, making it reliable even in heavy rain or when launching near water. You won’t find corrosion or condensation behind the lens—just consistent performance you can count on.
Visibility means safety, and with a PC rating, this light throws a 180-degree beam pattern that covers both front and side angles. Mounted properly, it works as both a clearance and side marker light, creating a solid panel of red illumination that’s easy to see head-on or from either side. It meets DOT and FMVSS 108 requirements for added peace of mind on the road.
Getting this light mounted is straightforward. At 2" in diameter and 1-1/2" deep, it installs neatly using a black PVC grommet (part #146-18, sold separately) for a recessed fit. It accepts the industry-standard 2-prong plug (part #142-49, sold separately), so wiring is quick and tidy without custom work. Once it’s in place, you get a smooth fit that looks factory-made and stays secure.

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look at this Peterson Submersible Round LumenX LED Clearance and Side Marker Trailer Light. Now, this LED trailer light is going to function as both a clearance and side marker light when properly mounted. It does not require top-mount position to meet the Department of Transportation requirements for PC rating. Now, as you can see, even with my bright studio lights on here, I have this connected to power. You can see just how bright this is, even with my lights on, but lemme go ahead and turn my studio lights off here while we're close up just to give you a better idea of what this is gonna look like in low light or dark conditions.
LumenX optics creates a solid panel of light that's going to light up the entire lens, as you can see. And as you know, LEDs make great replacements for incandescent lights. They last up to 50 times longer. They're more efficient, they give you brighter light with less power output, so no bulbs to replace, no brittle filaments to worry about. And I'm gonna go ahead and zoom out just to show you what this is gonna look like from a distance, and while I keep my wires together here, lemme just see if I can shine this on the wall behind me just to kind of give you an idea of how much light this is going to actually emit outwards.
So, the regulated design is going to ensure consistent light output, it's gonna prevent overheating. I'm gonna go ahead and turn my lights back on, go back in for a closeup again, and then lemme go ahead and disconnect the power so I'm not continuing to blind you here. And now, this does have a red lens over five LEDs. It's sealed, so that's gonna make this waterproof and submersible. It's gonna be very durable.
Lemme get my ruler here, go over some measurements with you. So, looking at the overall diameter, lining that up there, right at two inches, as you can see, and then including the socket, about an inch and a half deep. And if you don't have one, we do carry the recessed mount with black PVC grommet, and you can find that on the Related Product Section on this product page, and the model number of that is 146-18. And this does, as you can see, accept the industry standard two-pronged plug. If you are also in need of that, that's model number 142-49.
So, again, for that PVC grommet, it's 146-18, and for the two-prong plug, it's 142-49. So, this will be compatible with your 12-volt DC systems. It is DOT-compliant, and it does meet the Federal Motor Vehicle Safety Standards 108 requirement for automotive lighting and it is PC-rated. Well, I think that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
