Features to know about

Brighter and More Efficient Lighting: 3-Diode LED Design

This mini LED light gives you bright, reliable visibility without the high power draw. It uses three red LEDs that only pull 0.06 amps at 12.8 volts, so you get strong illumination while keeping your system efficient. Compared to old incandescent bulbs, these LEDs shine brighter, last up to 50 times longer, and don’t need bulb changes or worry about brittle filaments.

Confidence in Wet Conditions: Sonically Sealed and Submersible

If your trailer ever hits rain or water, this light is built to handle it. The polycarbonate lens and housing are sonically sealed into a single waterproof unit, keeping moisture out and protecting the diodes from corrosion. It’s fully submersible, so you can launch or pull your trailer through wet environments without worrying about shorting out your lights.

Better Side and Clearance Visibility: PC-Rated 180° Coverage

This light throws a wide 180-degree beam pattern for clear visibility from the front and side. The PC rating means it can serve as both a clearance and side marker light when properly mounted, adding safety by making your trailer easier to see from multiple angles. With this setup, you get improved awareness for both daytime and nighttime travel.

Simple Mounting Anywhere You Need It: Compact Surface Mount Design

At just 2-1/2" long by 1-1/8" tall and 5/8" deep, the low-profile rectangular housing fits into tight spots without sticking out. It surface mounts flat against your trailer—no cutout required—and can be installed horizontally or vertically with standard hardware. The 2-wire pigtail makes wiring easy: one lead for power and one for ground.

Durable Build That Lasts: Polycarbonate Lens and SMT Circuit Board

The light’s polycarbonate housing and lens stand up to vibration, shock, and daily wear. Inside, surface-mount technology keeps the LED circuit board stable and distributes heat evenly for longer life. It’s a tough little light designed for years of dependable use, backed by a lifetime warranty on the LEDs.

Video Transcript for The Low-Down on the Mini LED Trailer Clearance and Side Marker Light

Speaker 1: Today we're taking a look at the Optronics Mini LED Trailer Clearance and Sidemarker Light.This small trailer light functions as both a clearance light and sidemarker light when properly mounted. It is SAE and Department of Transportation compliant.It features a sonically sealed design. So, that means that it is completely waterproof. It is submersible.It is an LED system. LED has been a great replacement for incandescent lights. They last longer.

They burn brighter. They're more efficient. With LEDs, you don't have to worry about replacing bulbs or worry about brittle filaments.It has a nice red lens for looking at a polycarbonate lens and housing for strength and durability.It's a direct surface mount installation. Mounting hardware not included, but it mounts directly on the surface of the trailer. Can be mounted horizontally or vertically, whichever works best for your application.It's a two wire design.

So our white wire is our ground wire. Black wire is our power wire. It is P2PC rated.We're going to go over the measurements real quick and then we'll hook it up to power so you can see what it looks like with power running to it.Going edge to edge, this direction, it measures about two and a half inches. Top to bottom, measures about one and one-sixteenth to one and one-eighth inches. The overall depth is only about five-eighths of an inch deep or thick.

So it's a nice low profile design. The mount holes on the unit are separated on center by one and three-quarter inches.We're going to go ahead and hook it up to power. That way you can see what it looks like with power running to it. We'll also turn off our overhead lights, so you can see it in a lower light setting.This light sends out a nice, clear, consistent signal. It features a multi-diode design.

So the unit actually has three LEDs internally. So the multi-diode design really helps optimize the overall light output. The power draw at 12.8 volts is 0.06 amps and Optronics puts a lifetime warranty on the LEDs.That's going to do it for today's look at the Mini LED Trailer Clearance and Sidemarker Light.

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:

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

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.

See what our Experts say about this Optronics Trailer Lights

  • Do You Have The Optronics Mini LED # MCL14RB With a Plug Style Connector?
    The Thinline LED Trailer Clearance # MCL66RPG is the closest light we have to the Mini LED # MCL14RB with any kind of connector on the end. As you most likely have the Male 2-Wire Plug # A46PB on your trailer you can wire the Mini LED # MCL14RB with the Female 2-Wire Plug # 153-49 so that you will still be able to use the plug connectors. If you have a different style plug connector please let me know which style connector you have and I can see what is available.
