Features to know about

Brighter, Longer-Lasting, and Efficient: LED Trailer Light

Tired of replacing filament bulbs that burn out or fade fast? This rectangular LED clearance or side marker light uses two red LEDs that last up to 50 times longer than traditional bulbs. At 12.8V, it only draws between 0.05 and 0.07 amps, giving you a bright, crisp output without overloading your system. You get dependable illumination that stays clear and consistent for the long haul—no bulbs to swap and no fragile filaments to break.

Worrying About Water Damage: Fully Submersible and Sealed

If your trailer gets wet or even goes underwater, this light can handle it. The housing and clear lens are sonically sealed together into one waterproof unit, keeping water out and protecting the diodes from corrosion or failure. Whether it’s rain, spray, or full submersion, this light stays sealed tight and shining bright.

Poor Visibility at Night: Versatile P2/PC Rated Coverage

Visibility matters when you’re out in low light. Mounted vertically, this light’s P2 rating gives a focused 90-degree beam spread for strong forward visibility. When mounted horizontally, its PC rating provides a full 180 degrees of coverage so it can function as both a clearance and side marker light. Either way, it makes your trailer easier to see and safer on the road.

Straightforward Mounting: Compact Surface-Mount Design

Installation is simple with this 3-11/16" long by 13/16" wide by 3/4" thick light. It surface mounts using 3" center-to-center holes and connects with a 9" self-grounding pigtail. That means fewer wires to manage and no complicated grounding setup—just mount it, plug it in, and you’re good to go.

Durable Construction for Long-Term Use: Polycarbonate Housing and Clear Lens

Built for the elements, this light uses a tough polycarbonate housing with a clear lens over red LEDs. The durable materials resist impact and UV damage while keeping the light looking clean and sharp over time. It’s DOT compliant and comes with a lifetime warranty on the LEDs for extra peace of mind.

Video Transcript for All About the LED Trailer Clearance or Side Marker Light

Hello neighbors. Today we're looking at our LED trailer clearance or side marker light, and it's a submersible two diode red color with a clear lens. Now folks, this rectangular LED mini trailer light does function as both a clearance light or a side marker whenever properly mounted, it's been sonically sealed, so the waterproof housing and lens unit is submersible. The LEDs make great replacements for your incandescent lights and they last 50 times longer on average. They're also more efficient. They provide brighter light with a lot less power output.

You don't have to worry about bulge or replace the brittle filaments that pop sometimes over bumps and stuff in the road, and it's got a nice durable polycarbonate housing and lens assembly. And again, it's a clear lens over the two red LEDs. It does work with 12 volt DC electrical systems and it simply surface mounts to the trailer. Now you will need your own hardware. You can see this side over here has the built-in ground already in place.

When you put that screw nut bolt or whatever through there, it's gonna ground it to the trailer frame, giving it the ground it needs. And then you simply just have to hook up a power wire. Has a nine inch pigtail here included with it. I've got it kind of plugged in here with this other alligator clip for demo purposes. And it's DOT compliant and it's also P2 rated if it's mounted vertically or PC rated if you mount it horizontally.

So I'm gonna go ahead and light this up for you and we'll even turn the overhead lights on and off here in a second to show you both ways. All right, so in the daytime, you can see nice bright two diodes. I turn off the overhead lights and I'm just gonna kind of flash it just to kind of show you and then back in the daylight. So again, nice little clearance light or side marker light here. This is again the LED with two red LEDs and the clear lens, has a lifetime warranty on the LEDs themselves and has a nice power draw of only 12.8 volts as 0.05 and 0.07 amps.

I'm Steven, thanks for watching and have a great day.

  • 2-1/2" Long Submersible Clearance Lights With Clear Lens and Red LED For Boat Trailer
    Hey Zach, I have a solution for you, but the Thinline LED Clearance and Side Marker Light - Submersible Red # AL91RB and Thinline LED Clearance and Side Marker Light - Submersible Amber # AL91AB aren't available in clear lens with red LED. These units are typically found on light bars like the white with Red Lens # MCL84RB or black with Red Lens # MCL93RB. These are all submersible. That said, we do have some submersible clear lens with red LED that are also 2.5": - # TN52XR - # MCL13CR2B -...
