Command Electronics K-51 Amber LED Clearance Light with Reflex Reflector Measurements

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.


Surface-Mount Light

Surface Mount Trailer Light Installation Diagram

Surface-mount trailer lights install using a flange or bracket with mounting holes. These lights lay flat against the trailer surface and only require a small, often pre-existing hole, for wiring. Mounting hardware is used to secure the light to the trailer.

Video Transcript for Command Electronics Trailer Lights - Clearance Lights - 328-K-51 Review

Presenter: Today we're taking a look at a LED clearance or side marker light with a built-in reflex reflector. This small, oval trailer light serves as either a side marker light or a clearance light. It is a LED system. LEDs make great replacements for incandescent lights. They last longer, they burn brighter, and they're more efficient. With LEDs you don't have to worry about replacing bulbs and you don't have to worry about brittle filaments.Now this light has a nice amber lens with a built-in reflex reflector, mounts directly on the surface of your trailer, hardware not included and it can be mounted horizontally or vertically.

Whatever works best for your application. The holes are pre-drilled here in the base and to gain access to those you just need to pop the lens off and then once you install it, the lens snaps back on into position. It's a two wire pigtail so it includes your lead and ground wire. Ground is white. Power wire's yellow.

It does require at least a three quarter inch diameter hole here for the wire base to fit into to. So again, a three quarter inch diameter hole is required at the insulation surface for this area right here to fit into. You can see how that sticks out. And that would be for a flush mount or surface mount design. It is SAE-approved and it is a PT-rated light.Taking a look at the overall dimensions real quick, starting with the overall length measuring edge to edge.

Very close to four inches, maybe three and 15/16ths. Right in that area. The overall height or width, depending on how you have it installed, is one and five eighths. And then the overall depth, that's how far it sticks out from the installation surface, is a half inch. And then these mount holes are separated on center by two and a half inches.We're gonna 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 be able to turn off our overhead lights so you can see it in a lower light setting. So you can see here the light sends out a bright, consistent signal. This unit contains two LEDs or two diodes. So the multi-diode design really helps optimize the overall light output. And with the light turned on, you can get a really good look at that built-in reflex reflector that's built into the lens.And that's gonna do it for today's look at the LED clearance or side marker light with the built-in reflex reflector.

The trailer light that was ordered was the perfect fit. The product description and dimensions provided were very helpful to ensure I was ordering the right product the first time. The assistance provided to a question I asked was also very helpful and saved me time on installation from the previous ones I ordered. Will definitely be coming back when anything else is needed for our camper. Thanks! 853723

As always, eTrailer’s products are just as advertised and their service is excellent. In my most recent purchase, I reached out to eTrailer because my order was slow to arrive. Even though the delay was no fault of eTrailer’s, they took the time to review the shipping process and get me a thorough update for the delivery. I will gladly continue to do business with them and recommend eTrailer highly. 848065

Perfect exact replacement for newer Thor motorhomes with LED clearance marker lights. I bought an extra one to have on hand and installed another to replace a non-functioning one. Looks just like the original and mounts to the same screw holes. Of course, etrailer's rapid shipping is always nice too! 711082

Ask the Experts about this Command Electronics Trailer Lights

  • Replacement Clearance Lights Needed for GLO-BRITE 122R and 122Y Lights
    From what I could find it looks like your 122R (red) and 122Y (amber) lights measure 3.75" x 1.70" x .81". We don't have any replacement lense directly for the GLO-BRITE lights but we do have some similar lights that you could use as replacements. I recommend checking out the Command LED lights # 328-K-51 for amber and # 328-K-52 for red. These measure 3-3/4" long x 1-5/8" tall x 1/2" deep and have mounting holes that are spaced 2-1/2" apart on center. Attached are links to review...

  • What is the Mounting Hole Spacing for LED Clearance/Marker Light 328-K-51

  • What Type of Trailer Wiring Connector Clamps Down to Connect to Wires
    Sounds like you are describing quick splice connectors like the part # SWC501925-1 which are a pretty standard and easy design most of the time. To make the connection you just set the two wires in the slots and use pliers to close the lid and your set. This part number actually strips the wires too.

  • Installing Side Marker Clearance Lights with Two Wires on Trailer
    The Bonded 4 Wire - per foot # 16-4B-1 you asked from would use the brown running light wire for your clearance/marker lights. The LED light you referenced sound like they have two wires so one will be power and the other ground. You can connect them to a battery to test which wire is power as LED lights are polarity sensitive. It is likely the yellow is power and the grey is ground which will be attached to the base frame or metal frame structure on your trailer. Often the clearance/side...

  • How Does The Chrome Trim Ring Fit The Command LED Clearance Lights
    The Chrome Trim Ring for Command Electronics Oval LED Clearance or Side Marker Light part # 328-89-386 does just snap over the lens of the LED Trailer Clearance or Side Marker Light with Reflex Reflector part # 328-K-52 or part # 328-K-51. You are correct about the videos, I will put in a suggestion for a video that demonstrates both the light and the ring.
