Older incandescent trailer lights can dim or overheat, but this Peterson LumenX LED trailer light keeps things cool and bright. The integrated voltage regulator maintains consistent light output over a 9V–16V operating range without overheating. With seven white diodes shining through a red lens, it produces bright brake and turn signals and a clean glow for tail light mode—all while drawing just 0.37 amps at 12V for stop/turn and only 0.01 amps for tail. It’s efficient, long-lasting, and ready to shine every time you hit the brakes.
Voltage spikes can wreak havoc on LEDs, but this light’s regulated design provides voltage protection across your entire system. It ensures steady brightness and dependable operation whether your trailer is idling or under heavy electrical load. You get consistent light performance that meets FMVSS 108 standards without worrying about flicker or premature wear.
No need to hunt for a custom bracket—this round 5-1/2" light mounts flush to the surface using the built-in flange. It requires a 4-1/2" cutout, and the distance between mounting holes is 4-1/4" center-to-center. The AMP-style plug connection keeps wiring simple and secure. Hardware isn’t included, so you can choose fasteners that best fit your setup.
Moisture is the enemy of dependable lighting, but the skirted weld joint on this housing helps block water from creeping in. Even though it’s not submersible, that extra bit of sealing keeps performance reliable through rain or road spray. It’s a solid choice for anyone wanting durability and bright output without worrying about corrosion or leaks.
This round LED tail, brake, and turn signal lamp meets FMVSS 108 requirements for visibility and safety. With bright optics that fully illuminate the red lens, it provides clear signaling from any angle. When you need a light that looks good, works hard, and stays compliant—this LumenX LED has you covered.

Ellen: Hey everyone. I'm Ellen, here at etrailer.com and we're taking a look at the Luminex LED Trailer Light. This is going to be for your stop and turn and tail light. So it gives you all three functions in one light housing. It is an LED light, so it's going to be a lot longer lasting than your typical incandescent bulb, requires no maintenance as well, since you don't have to change out any bulbs ever. And it should be a really nice rugged light for you, for just about any kind of application.
I have it already illuminated here. So this is going to be our tail light signal or our running light signal. If I hit the button on my little power box, that would be for our brake, or also our turn signal.You can take a little closer look at the light. You can see it already is in this housing to give it a little bit of a more finished look. And this has the Luminex optics, so it's going to make a more solid looking light.
Especially whenever it's completely illuminated, like if we're hitting the brakes or using our turn signal. I'll turn the light out in the studio, just a second, and back up a little bit so you guys can see that a little better. So that's just our running light signal. You can see how bright that is, so not terribly bright, but enough that other drivers would be able to see us whenever our lights are on in the dark or during a rainy day. And then, we hit the brakes it's going to be brighter still.
So it's going to give us our more full brightness for that light.I like the design of this. It looks pretty cool, in my opinion. It just looks interesting with that seven concentric circles going around. Turn the lights back on, and we can talk about the measurements and also about how this is actually wired up. So you can see I have this plug going to the back, pretty easy to use.
This is a plug that you can find here at etrailer.com. It is sold separately. It's going to be a related part on the product page. So you just wire up your signals to that. Red wire will be to your turn and brake signal. Black wire is your 12 volt power, or your running light power. And then the white wire is your ground. So pretty straight forward. Set that off to the side.And then as far as the diameter of the light, this is going to fit into a four and a half inch hole. So it needs a four and a half inch opening to fit in place. The light face is about four and a quarter inches in diameter. The overall diameter, or the outside dimension, is about five and a half inches. The depth for the light is about seven-eighths of an inch. If we include our wiring portion, it's about an inch and a half. So at the most, it's an inch and a half deep. Again, has a total of seven diodes there to give us that pattern on the light. The power draw at 12 volts for our stop and turn signal is 0.37 amps for the tail light signal. It's just 0.01 amps. So very low power draw. Shouldn't have to worry about it overloading a battery, or draining your battery too quickly. You can have a bunch of these and still be able to power it up pretty well.The operating voltage goes between nine and 16 volts. So it works with DC power. There is a limited lifetime warranty on this. It is DOT compliant. Made in the USA. Will have a red lens over white LEDs. So pretty nice looking light overall, in my opinion. One last measurement I want to give you, the mounting holes. The distance between those, center to center, is about four and a quarter inch going across. There's three mounting holes. It does not come with any hardware, so you will have to pick that up on your own. And the diameter on that is about a quarter of an inch. So anything a quarter of an inch or smaller should work okay.That's going to do it for our look at the Luminex LED Trailer Light. I hope this video has been helpful in deciding if this is the right light for you. And thanks for watching.
