Features to know about

Brighter Lighting with Less Power: Efficient 1-Diode LED Design

Old incandescent bulbs can dim over time and waste energy, but this mini LED light puts out a clean, bright amber glow while using only 0.082 amps at 12.8V. The single-diode setup keeps things simple and efficient, giving you reliable light that lasts up to 50 times longer than older bulb types. There’s no filament to break, no bulb to swap, and less power draw on your system.

Protected from Water and Weather: Fully Submersible Construction

Moisture is the number one killer for trailer lights, but this 1-1/2" round unit is built to handle it. The lens and housing are sonically sealed together, creating a single waterproof piece that’s completely submersible. Whether it’s rain, road spray, or launching at the ramp, the sealed design keeps water out and the LED working like new. The included gasket helps form a tight seal against the mounting surface for extra protection.

Better Visibility All Around: PC-Rated 180-Degree Coverage

Visibility matters when it comes to safety. This PC-rated light spreads its beam 90 degrees to each side of center for a total of 180 degrees of coverage. Mounted properly, it works as both a clearance light and a side marker light—visible from the front and sides so others can see your trailer from more angles. That means better awareness in traffic and at night.

Clean, Secure Mounting: Recessed Design with Locking Ring

A recessed mount gives a neat, flush look while protecting the light from getting bumped or snagged. This model uses a stainless steel locking ring that holds it firmly in place and deters theft. The compact 1-1/2" diameter body fits easily into pre-existing holes or new cutouts, keeping installation tidy and straightforward with its simple 2-wire design featuring 0.180 male bullet connectors.

Built to Last: Durable Polycarbonate Lens and Housing

Rough roads and long hauls are no match for this tough design. The clear polycarbonate lens over an amber LED resists cracking and clouding while staying bright over time. It’s DOT compliant, compatible with 12V DC systems, and backed by a lifetime warranty on the LEDs—so you can count on it to stay bright trip after trip.

  • PC-rated light coverage: Produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

  • Recessed-mount installation: Trailer lights install with a grommet, which is often sold separately. These lights extend past the trailer surface and require a hole for installation. If replacing a light, you can utilize the pre-existing hole. If installing a new light, you will need to cut a hole or use a mounting bracket (sold separately) to complete the installation.

Video Transcript for An In-Depth Look at the Mini LED Clearance and Marker Light w/ Locking Ring

Today we can take a look at the mini LED submersible clearance and marker light with locking ring. It's an Amber LED with the clear lens.Now this small round trailer light will function as both a clearance light or a side marker light when properly mounted.It's sonically sealed waterproof housing and lens unit is submersible has a stainless steel locking ring that will secure the light and prevent theft. And it's an LED so it makes great replacements for incandescent lights because the LEDs last 50 times longer, they're more efficient, provide brighter light with less power output and no bulbs to replace or no brittle filaments.It's a durable polycarbonate housing and lens. It is a clear lens over an Amber LED. It is compatible with 12 volt DC systems. It is a recessed Mount with the locking ring.

And then right there, the black portion is the gasket which will help create a nice weathertight seal.The wires you can see. The two-wire design with the male bullet connectors. It is DOT compliant. PC rated.A few specs on this, I want to give you some measurements. The overall diameter, including that locking ring is one and a half inches.

The thickness from the front to the back is right at seven eighths of an inch. And just the light face itself is about three quarters of an inch diameter.It is one diode. Power draw at 12.8 volts it's 0.082 amps, and they do have a lifetime warranty on the LEDs. What I'm going to do now is hook this up to 12 volt power and show you how bright the light is.So we'll go ahead and take our power, our ground, and then our power wire. And with it hooked up, I'll go ahead and turn on the power and you can see the bright Amber LED.

I'll go ahead and turn off the overhead lights and you can see for one LED, it gives great, good, bright light out of it.Turn back on our overhead light, turn off our power, but that should do it for the review on the mini led submersible clearance and marker light with locking ring, Amber LED and a clear lens..

Bought the Optronics Sealed Trailer Light, UL95CB, as a replacement for my boat trailer's backup light and paired it with a Optronics Mounting Bracket, A91BB. The combo was a perfect replacement and fit. Installation was easy with stainless steel rivets. Etrailer.com had the best price BY FAR and the products were received prior to the estimated delivery date.

I have had earlier model , with stainless housing,, this new one has plastic chromed housing. Cheaper to make. The first one lasted 8 plus years .



by:

Excellent quality



by:

I would have liked them to be just a little bigger but were what I wanted but will be returning with fenders.



by:

lights are bright and shine in a perfect 180 degree pattern



by:

LPL31CB as used in the flameless heat generators we build for Rain for Rent (used in the natural gas industry). Looks good, works fine, lasts a long time!



by:

The right part delivers on time



by:

exact replacement for my vexus trailer



by:

Perfect ... This clearance light was for a vintage Holsclaw motorcycle trailer ... can’t get any better than this ...
Replaced the old style with new style ...



by:

These guys are good,we build a few trailers in our shop, & these guys have the inventory, you get it fast & you can get them on the phone, we need more outfits like this to do business with! Thanks Guy's--



by:

The product has apparently changes. The part number is the same as what I purchased in the past but these are NOT the same marker light, they are cheap knock-offs. Not even close to the same light. See attached picture, the one on the left is what this part number used to be, the one on the right is the cheap replacement that was sent. Will be returning. It’s too bad I can no longer get the same quality light to match the others on my trailer.



by:

Exactly what I ordered and expected with fast shipping!



by:

easy to install and works great



by:

So far these led flush mount lights are working great. They're bright and a refreshing update over old incondesant lights. I got these to put on an older camper I purshased. From the photos you can see what was on the camper and I what I upgraded to. The old lights were dull and could barely tell they were lit. These lights bring a modern day update to an 1989 camper. Besides the product being good the shipping was fast and free. And I also like that on etrailers site when your package is in shipment they have a map of the US showing where your package is.



by:

This side marker light is a replacement to an existing one. It is an exact replacement. The new light is spot on to the one I installed about 4 years ago. Good quality. It see’s salt water continuously.



by:

Very strong led light. And very multi purpose. Built a toy hauling trailer for a friend that need some extra light for loading up after dark, and liked to be able to keep a eye on his load after dark. These worked out great, also used some to light up some quads. Very bright for as small as they are. Oh and there are 26 lights on the trailer. Lol no problems with any of them.

Perfect Replacement for marker lights on my 2016 Backtrack trialer for my Xpress boat.



by:

A couple of years ago, I converted a single jet-ski trailer to a kayak trailer to hold my two kayaks, and installed new LED stop/turn/brake lights and clearance lights from etrailer.com. The lights worked great, and I used the trailer for a couple of years before I realized that I was missing a light for the license plate! I'm surprised I never got pulled over by the police! etrailer.com came to my rescue again with this great LPL31CB license plate light. It's very bright and really lights up the plate and the ground around the back of my trailer. Recently I added three more small red clearance lights at the back of my trailer, so the tailgaters and crazy drivers have no excuse about seeing my trailer! See the pictures! etrailer.com has great products, great service, and fast shipping!



by:

Perfect fit replacement. Delivered quickly at a great price. Easy install and safely back on the road.



by:

I purchased this light to replace a cargo trailer light. It isn't a exact match but pretty close. It gets the job done and unless you know the light is different no one will know. Light looks the same as the original.



by:

LED license plate light really lights things up



by:

The replacement lights are exactly the same as original. Other online offerings were similar but would have required modification. Pricing was competitive as well.



by:

Were a perfect match for the clearance lights on my 2015 American Hauler trailer.



by:

So far this license plate light has worked flawlessly! The only reason I didn't give it 5 stars was that I thought the original light (same or very similar light) would last "forever" considering how much we use the trailer. In any case, this light thoroughly illuminates the license plate, so it's easy to see for the toll cameras in our area! I really appreciate the support and products that etrailer supplies. The other lights on my trailer (tail, turn, brake, clearance) have worked great, as long as I maintain a good ground connection on the wiring! I recently had a problem with intermittent lights (blinking on and off), that I eventually traced to a bad ground wire INSIDE the trailer-side wiring connection. I replaced the trailer-side connection, re-spliced the other wires, and wired everything through a weatherproof junction box that I bolted (drilled and tapped) to the side of the trailer tongue. The new ground wire is fastened securely to one of the threaded/bolted connections and seems to be working well so far. I used wired nuts to connect the other wires inside the weatherproof box, so it will be easy to replace connectors if they fail in the future.
