Features to know about

Brighter and Longer-Lasting Light: 10-Diode LED Design

No more dim bulbs or constant replacements. This 2" round LED light uses ten white LEDs behind an amber lens to put out a bright, even glow while drawing very little power. Because it’s LED, it lasts up to 50 times longer than an old incandescent light and never needs a bulb change. It’s fully compatible with 12V DC systems, so it runs efficiently without adding strain to your wiring.

Protected From Water and Weather: Fully Sealed and Submersible

If your trailer ever gets wet or goes underwater, this light is built for it. The housing and lens form a sealed, waterproof unit that keeps water out of the circuit board and diodes. It’s dependable anywhere moisture might sneak in—from rainy roads to full submersion at the ramp. The durable polycarbonate lens also holds up against knocks and road debris for long-term reliability.

Better Visibility and Compliance: P2-Rated 90-Degree Beam Pattern

Visibility is key for safety, and this light’s P2 rating means it shines with a controlled 90-degree beam pattern—45 degrees to each side of center. That’s ideal for use as either a clearance light or a side marker light, making your trailer easier to see from the right angles while staying DOT compliant.

Clean Install Every Time: Simple Recessed Mounting

Mounting doesn’t have to be complicated. This compact 2" diameter by 7/8" thick light fits neatly into a recessed grommet mount (sold separately) for a clean look that stays out of the way. It connects with an industry-standard 2-prong plug, so wiring is quick and straightforward with no guesswork or custom fittings needed.

Video Transcript for Hands-On with the Custer LED Side Marker or Clearance Trailer Light

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this LED side marker or clearance trailer light. This is a DOT compliant two inch diameter round trailer light that will serve as either a clearance or a side marker light. This is P2 rated so it is going to produce a 90 degree beam pattern so 45 degrees on either side of the center line. So this can work as either a side marker light or a clearance light, but it won't be able to do both at the same time so you wanna make sure that you're mounting it in the appropriate location. This does have a sealed housing and polycarbonate lens that's going to provide nice durability and ensure it's going to be waterproof for you.

So you can put this on a boat trailer. We do have the amber lens over these tin white LEDs and those LEDs are gonna be great, if you're not familiar with the difference between LEDs and incandescence, the LEDs last about 50 times longer because there's no brittle filament like with your incandescent lights, so you're not gonna have to replace the bulbs and they are gonna be more efficient so they provide brighter light with less power output. Now this is gonna be compatible with your 12 volt DC system. It accepts the industry standard two prong plug. It is right about 7/8 of an inch thick and it is compatible with the grommet so that it can be recess-mounted and that grommet is sold separately but you can find it here at etrailer.com, should be a product listed on the product page as a related product for this.

So if you are wanting to replace a side marker or clearance light for your trailer, then this is gonna be a great option for you. That completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

Surface bracket no longer available, doesn't come with wiring either

They fit perfectly and work as they should. They also arrived on time! Thanks



by:

Excellent. This has to fit into a rubber gasket between the light and the trailer fender. If the size is even slightly off it won't work.



by:

These are really nice marker light for a replacement on oour motohome.



by:

The light works fine, but it did not come with the hardware to install it. It doesn't help having the light working fine on the workbench when there is no way to attached it to the trailer.



by:

Bright, high quality and waterproof. Probably the best quality replacement for running lights of similar size. My only complaint is that there is no base plate. The light is exactly as shown in the photo. But, since there are no replaceable bulbs, I guess it isn't necessary.



by:

Look great and work like a charm



by:

Excellent product. Perfect fit



by:

Perfect replacement size for broken light made for easy install. Very bright. Did not review quickly due to waiting to actually submerse the light. Id is indeed submersible and is noticeably brighter than the original light on my boat trailer. And shipping was impressively quick. Thank You!
