Features to know about

Brighter, Longer-Lasting Visibility: LED Trailer Light

Older incandescent bulbs fade fast and pull more power. This 2-1/2" x 1-1/4" rectangular Custer LED light uses three bright white LEDs behind an amber lens for solid, efficient illumination. The LEDs last up to 50 times longer than standard bulbs and draw less current, so you get strong, consistent light without worrying about burned-out filaments or high power demand. It’s the kind of upgrade that instantly improves visibility without adding maintenance.

Tough Enough for Harsh Conditions: Durable Polycarbonate Build

Road grime, vibration, and moisture take out weaker lights fast. This one is built to handle it. The housing and lens are made from durable polycarbonate that resists damage from impact and weather. It’s also submersible, so water and dirt won’t creep in and ruin the LEDs. Whether you’re on wet roads or working in rough environments, it stays sealed and dependable.

Simple Mounting for Different Setups: Surface or Recessed Options

Mounting flexibility makes setup easy. You can surface-mount this light with a snap-in bracket (not included) or go with a recessed grommet mount (sold separately). It accepts the industry-standard 2-prong plug, which means wiring is straightforward and connects cleanly with common trailer systems. That makes it simple to install in custom builds or as a direct replacement—just plug in and go.

Safe and Compliant Performance: P2 Rated Beam Pattern

Visibility isn’t just about brightness—it’s about coverage. This P2 rated light projects a 90-degree beam pattern that works perfectly for side marker or clearance lighting. It meets DOT requirements, giving you peace of mind that your trailer lighting is up to spec while improving safety on the road.

Video Transcript for All You Need to Know About the Custer LED Side Marker or Clearance Trailer Light

Today we're going to take a look at the Custer LED amber side marker or clearance trailer light. Now this is a nice rectangular trailer light that can serve as either a clearance or side marker light. It is P2 rated, so it does produce a 90-degree beam pattern, and it is DOT, department of transportation, compliant. This light does use LEDs. They make great replacements for incandescent lights. They'll last about 50 times longer.

They're more efficient because they'll provide brighter light with less power output and, of course, no bulbs to replace or brittle filaments that are going to break. It's a nice durable polycarbonate housing and lens. And if you notice, the lens is amber color over three white LEDs. This is compatible with the 12-volt DC systems.There's a couple of ways you can mount this. You can surface mount this light with a snap and bracket, which we do sell separately on our website.

It's part number G26B-C. And you can also recess mount this with a rubber grommet, which we sell separately. Part number G26G. And both those items are listed on this product page as a related product. And if you look on the back, you'll see the two connections there.

It accepts the industry standard two-prong plug, part number GP-1.So what I'm going to do now is we're going to hook this up to some 12-volt power and then turn off the lights just to show you how bright it is. So I'll first go ahead and take one of them. We'll hook it up, and we'll go ahead and hook the other one up. And with both of those hooked up, I'll go ahead and turn off the overhead lights. And here you can see the three LEDs gives you a very bright light for a small light that it is.

Then we'll go ahead and turn back on our overhead lights, and we'll disconnect it.But that should do it for the review on the Custer LED amber side marker or clearance trailer light.

  • What Size Hole do I Need to Cut to Install the Grommet Part Number G26G ?
    Hello Mark, Your cutout is going to be 2-5/16" x 1-1/16". The # G26G rubber grommet fits into a 2-5/16" x 1-1/16" hole, securing the # CPL26-A clearance light. The grommet holds the light by gripping its edges, while the light's larger front face rests against the outer lip, preventing it from passing through. This setup ensures a secure, flush-mounted installation while allowing for easy removal or replacement. Let me know how the installation goes. Are you replacing lights on an old...

  • Surface Mounting Bracket For Custer LED Side Marker/Clearance Light CPL26-A
    Hi Adam! We do have another option that will fit the exact same way, but I am sad to say the Custer bracket is no longer available. The Custer LED Side Marker or Clearance Trailer Light # CPL26-A snaps into the Optronics bracket # A91CB perfectly (almost too perfectly as it took a slot screwdriver and some patience to get it out when I test fit them together). Unfortunately, it does only come in silvery chrome finished plastic, but it could very easily be rattle canned to whatever color...
