This Peterson LumenX LED back-up light packs seven white diodes behind a clear lens for strong, even illumination. The LumenX optics turn that output into a solid panel of light that fills the entire lens instead of showing single points, giving you clear visibility when backing up. At just 0.23 amps on a 12V DC system, it draws little power but still shines bright—a big step up from older incandescent bulbs that pull more current and fade over time.
Moisture is no match for this sealed LED light. The waterproof housing and skirted weld joint protect the electronics from water and debris, keeping performance steady through rain or wash-downs. A regulated circuit keeps the light output consistent and prevents overheating, adding another layer of dependability whether it’s mounted low on a trailer or exposed to the elements.
Mounting is straightforward with the recessed design that fits neatly into a grommet (Peterson 421-18, sold separately). It accepts an industry-standard 2-wire PL3 plug (Peterson 421-29, sold separately), so wiring is quick and clean without custom connectors. You can mount it in any 360-degree position to suit your setup.
Each LED lasts up to 50 times longer than a traditional bulb and never needs replacement. With no fragile filament inside, it’s tough enough for years of use without maintenance. It meets DOT and FMVSS 108 requirements for automotive lighting, so you know it’s up to standard. The 10-year limited warranty adds confidence that this oval 6-1/2" x 2-1/4" light will keep shining for the long haul.

Today we're taking a look at a Peterson Luminex LED backup light. This oval light functions as a backup light for your trailer work truck. It features durable surface mount technology when it comes to the construction of the led circuit board. That design better withstands shock and vibration and allows for improved heat distribution in a thinner construction.It is an LED system. LEDs make great replacements for incandescent lights. They last longer, they burn brighter, they're much more efficient.
With LEDs, you don't have to worry about replacing bulbs or worry about brittle filaments. It does feature a sealed design, so it is protected from the elements. It's a recessed mount installation with a mounting grommet and it also accepts an industry standard two prong plug.Both of those items, the grommet and the plugs are sold separately and available at etrailer.com. It is Department of Transportation compliant. It meets FMVSS 108 requirements for automotive lighting.
And the product's made in the USA. When it comes to the measurements of the light, we'll look at those real quick and then we'll hook it up to power.Edge to edge going this direction. It's about six and a half inches. Edge to edge going this direction. It's about two and one quarter inches.
All right, we'll go and hook it up to power. That way you can see what it looks like with some power running to it. We'll also turn off our overhead lights so you can see it in a low light setting.So when the reverse function is activated, you can see how this will eliminate, sends out a very bright, clear, consistent signal. We're looking at seven white LEDs with a clear lens, so it allows plenty of light to come through. And then the multi diode design really helps optimize the overall light output.
The input voltage for this unit is rated for nine volt to 16 volt DC. That's going to do it for today's look at the Peterson Luminex LED backup light.
