Features to know about

Brighter and More Efficient Lighting: 7-Diode LumenX LED Power

This oval LED tail light uses Peterson’s LumenX optics and 7 bright diodes to create a solid panel of light that covers the entire lens. It serves 4 functions—stop, tail, turn, and backup—so you get full coverage from a single, compact fixture. At 12V, it draws just 0.19 amps for stop/turn, 0.02 amps for tail, and 0.51 amps for reverse. That means brighter output with lower power draw compared to old incandescent bulbs and no filaments to burn out.

Clean, Integrated Design: Built-In Backup Light

Instead of cutting extra holes or wiring separate units for reverse lighting, this Cyclops-style design integrates the backup light right into the main housing. The red and clear lens over white LEDs gives you all four functions in one smart package. It’s a simple way to keep your trailer’s rear lighting clean, balanced, and easy to maintain.

Durability in Harsh Conditions: Sealed Against Moisture

The skirted weld joint adds another layer of protection against water intrusion, keeping the electronics safe and sealed. Combined with solid-state LED construction, that means no loose filaments or rusted sockets—just long-lasting performance that holds up through rain, road spray, and humidity.

Consistent Light Output: Regulated and Reliable

Integrated voltage regulation keeps brightness steady across the input range of 9V–16V DC. That consistent output helps prevent overheating while meeting DOT and FMVSS 108 standards for automotive lighting. Whether your trailer wiring sees voltage dips or spikes, the light stays even and reliable every time you hit the brakes or signal a turn.

Simple Mounting: Recessed Fit with Grommet and Plug

Installation is straightforward thanks to the included grommet and industry-standard AMP-style plug. The recessed mount design gives it a clean look while protecting the housing edges from knocks or scrapes. Measuring 6-1/2" long x 2-1/4" tall x 1-7/16" deep, it fits standard oval cutouts and can be mounted in any 360-degree position for flexible placement.

Video Transcript for Ultimate Overview of the LumenX LED Trailer Tail Light w/ Grommet and Plug

Today we're going to take a look at the Peterson Luminex LED trailer tail light kit. This is going to give us our stop, tail, turn and backup signals. This is going to have an oval design with a red and clear lens. As you can see we'll have our lights with that red lens and then our little Cyclops light there for our backup signal. That's going to give us that clear lens over that last diode there to provide the light for our backup. We'll also have a PVC grommet to go around our light that gives it a little bit more shock protection and just kind of cleans up the look of the light overall.

It's going to have a nice flex to it. That just goes over the back of our light.And then we'll also have two harnesses to go with our light itself. These are going to be industry standard AMP-style plugs and we'll have our smaller connection here. This is going to be our blue wire. That's going to be for the reverse signal or backup signal.

Just press that into place. And you'll notice on this one and our larger wiring, there'll be this little grommet. That's going to give it a little weather protection so we don't have to worry about any water, dust and debris from getting into our connections and causing any issues down the line. Of course it's never a bad idea to put a little bit of dielectric grease in there just to increase the longevity of your light but with that grommet, you almost don't even need it.If you want to pick up some dielectric grease, we do have that available here at etrailer.com. Something I like about this wiring style is that it clips over there and it's going to hold really securely on our light.

This larger clip is actually kind of tricky to get off. I was having to pry pretty hard on it to get it to come off but it does eventually. I'm going to connect this up to a power source here so you can get an idea of how bright this is going to be. Of course, the white wire with that ring terminal, it's going to be a number 10 ring terminal already installed. That's going to be our ground.

The black wire will be our tail light or running light signal.Turn that on. See our light will come on and then our red wire will be our stop and turn signals. It's going to be much brighter there. Our blue wire again, will give us that reverse signals. It's going to give us that bright white light that we need to see what's going on behind us and that does also work with our brakes or our turn signal if we ever would need those all at once. Go ahead and turn the lights out in the studio here so you can get a better idea of just how bright that's going to be. That white light is going to give us a lot of light to illuminate behind our trailer especially if we're working in the dark, and our brake or turn signal. Again, it's going to meet all DOT requirements. It's going to meet FMVS 108 requirements for automotive lighting. And turn our lights back on in the studio.And we'll go over some measurements with this. Now one thing, again to keep in mind with this, it is going to be an LED light so that means it's going to be a lot longer lasting than your incandescent bulbs. You don't have to worry about anything burning out over time. LEDs can last up to 50 times longer than your incandescent bulbs as there's no brittle filaments that can break and then blow out. There's nothing to replace with this so that's one less thing to worry about there. There's also surface mount technology with this so it's going to be better able to withstand the shock or vibration as you're going down the road. Again, that grommet is going to help with that as well and the SMT construction is also going to give better heat distribution inside the lens so we don't have to worry about our LEDs burning out.Again, as far as our dimensions, with the grommet in place it's going to be about 7-3/4 inches long by about 3-1/2 inches wide and then going from the front of the light to the back of our harness there, it's going to be about 1-3/4 inches deep. Just the light on its own is going to be 6-1/2 inches long and 2-1/4 wide by about 1-7/16 deep. Remove our plugs here and measure the leads. Again, that larger harness is a little trickier to remove. Not a bad thing. You don't want your wiring to come accidentally disconnected but . There we go. Okay. As far as our lead off of our reverse signal or our backup signal, it's going to have about 7-1/4 inches of length there and then for the rest of our wiring going to our red and black wire, it's going to be about 8-1/2 inches of wire.That's going to do it for our look at the Peterson Luminex LED trailer tail light kit. One last thing I do want to mention with this, is that it is made in USA.

Exactly what we were looking for. I do think the description needs to be more clear as I ordered an extra wire that actual came with the light. Other than that received the product earlier than expected and we were able to finish the job for the customer sooner.

  • Difference Between Peterson LumenX PE76UR and 880K-7
    Hi Rich; the # PE76UR is 7-11/16" long x 3-5/8" tall x 1-3/8" deep and uses a flange mount. The # 880K-7 is a different size at 6-1/2" long x 2-1/4" tall x 1-7/16" deep and comes with a grommet for a recessed mount. The connectors are also different. The lights themselves offer the same functionality and aside from the size have the same design.
