Older incandescent lights just can’t keep up with modern LED tech. This Peterson LumenX LED clearance and side marker light puts out a solid, even panel of red light thanks to its advanced LumenX optics. With five LEDs inside, it shines brighter and draws less power than traditional bulbs while running cool and efficiently on 9V–32V DC systems. It’s built to last too—up to 50 times longer than old-school filaments and with no bulbs to replace.
Uneven brightness or overheating can shorten a light’s life, but not with this one. The regulated design inside this 2-15/16" round light keeps the output steady and protects against heat buildup. That means consistent visibility and dependable illumination every time you hit the road, without worrying about dimming or burnout.
If your trailer sees rain, puddles, or even full submersion, this light is ready. The housing and red lens are sealed together as one waterproof unit, keeping moisture out and the electronics safe. You get the same bright performance whether you’re on wet roads or backing into the water—no leaking, no corrosion, just reliable light.
Visibility from all angles makes a big difference in safety. This PC-rated light produces a 180-degree beam pattern—90 degrees to each side of center—so it can serve as both a clearance and side marker light when properly mounted. Other drivers can see it clearly from the front or the side, helping everyone stay aware in low-light conditions.
Installing this light is simple and clean. It mounts in a recessed setup with a built-in black flange and accepts an industry-standard 2-prong plug (PET42PV – sold separately). The 2-5/8" center-to-center mounting holes make it easy to fit into existing setups or new builds without special tools or rewiring hassles.

Hi everyone, Steven here with etrailer.com. Let's take a look at our red Peterson LumenX LED clearance and side marker trailer light. Folks, it's submersible with a nice round polycarbonate lens. Everything's been sealed, it is waterproof, watertight. You will need to plug a pigtail to plug this in and wired up, sold separately. Item number PET42PV.
Again, sold separately and I've got one of them pulled, I'll show you here in a second. We'll wire this up and show you it lit up. Now this does not require top mounted position to meet DOT requirements for PC rating and the LumenX optics creates a night saw panel of light illuminating the whole lens itself. Center to center on these nine holes, you got two and five eighth inches. Overall, you got two and 15/16 in diameter and about one and one half inches deep.
The light itself is a two inch light, and this again is DOT compliant. So let's go ahead and get that pigtail again. That pigtail sold separately, it's a two wire. Again, item number PET42PV. And as you can see, it's got a nice waterproof gasket.
It simply plugs in the back here. It locks into place right there. It's a two wire. And let's go ahead and light it up here and take a look. And I'll go ahead and show off the overhead lights so we can see it better in the dark as well.
So you can see nice and bright, red LED makes it nice, visible, easy to see. I'm gonna zoom out and see if my camera will take this. There we go. So you can see from far away too just how bright and everything this is. And let's go ahead and turn the overhead lights back on and disconnect this now again, folks again. The pigtail's sold separately. It is a great addition. I highly recommend you pick one up if you don't have one already and you need one. So again, this is the Peterson LumenX red round LED clearance and side marker trailer light. I'm Steven. Thanks for watching.
