Features to know about
Reliable Lighting When You Need It Most: Bright and Efficient LED Design
This Optronics rectangular LED clearance or side marker light makes visibility simple and reliable. It uses 3 white diodes behind an amber lens that put out a crisp, bright glow while drawing just 0.051 amps at 12.8V. Even better, the LEDs last up to 50 times longer than incandescent bulbs, so you won’t be dealing with burnt filaments or frequent replacements. With that low power draw, it’s a solid upgrade for anyone wanting dependable trailer lighting that runs cool and efficient.
No Worries Around Water: Sonically Sealed and Fully Submersible
When your trailer meets the water, this light stays sealed tight. The polycarbonate lens and housing are welded together to make one waterproof unit that keeps moisture out. That sonic seal means you can dunk it during boat launches or drive through storms without worrying about corrosion or shorting out the circuit board. Once installed, it just works—rain or shine, wet road or ramp.
Simple Installations Every Time: Single Stud Mount and One-Wire Hookup
This light is built for quick installs with a single 1/4" diameter stud that doubles as the ground connection. Just tighten it down to a clean metal surface and connect the single 20" power wire to your running light circuit—it’s that easy. The stainless steel base keeps everything solid, and if you ever need to swap the bolt for a longer one, you can do that while maintaining a good metal-to-metal ground. No extra brackets or complex wiring needed.
Compact Size, Big Visibility: P2-Rated for Reliable Coverage
At only 2-1/8" long x 1-1/8" wide x 1-1/16" deep, this small rectangular light fits tight spots without losing function. Its P2 rating gives you a 90-degree beam spread—45 degrees each way from centerline—making it perfect as either a clearance or side marker light when properly mounted. That bright amber output helps other drivers spot your trailer clearly at night or in low-light conditions.
Durable Build That Lasts: Polycarbonate Housing and Lifetime LED Warranty
The tough polycarbonate construction resists impact and UV wear so the lens stays clear even after years on the road. Between that rugged housing and the lifetime LED warranty, this light is built to handle miles of use without fading or cracking. It’s a simple way to get lasting visibility with no bulbs to change, ever.

I want to thank you for all your help with my trailer you were more helpful than you realize. So this is my trailer for a 22' Flats Cat shallow draft Catamaran. I totally dismantled my trailer and buffed by hand with a wire buffer and sand blasted in some spots and applied multiple coats of some very expensive galvanize paint (Z.R.C.). I installed all new C. E. Smith Carpet (about 80'), seven new LED waterproof lights, new springs, new equalizers, new tongue jack, new wench, new safety chain, new chain brackets, all new SS hardware and a 35' long wiring harness.
I was able to send only one review with a picture of the safety chain and brackets. I'm having a little trouble with the rest..oh some of these items were bought locally or from your competitors, until I found ETRAILER. Your prices were cheaper for the exact same things. Your helpful how to videos were helpful. And Rose, your personal helpful knowledge made my buying experience very pleasant, I actually enjoyed talking to you! Thanks to ETRAILER and specifically to Rose G.

Installation is super easy. Much better than the flush plugs on the other options models. Lights brightly.
Specs should include the following:
Mounting hole needs 1/4 inch minimum, and nut is 10mm.

Very bright, very easy install; only reason for 4 stars is bc I just installed them and can't speak for their longevity; I drilled a small hole in my trailer next to the main mounting hole to poke the wire through, so as not to see the wire; looked very nice.

Very easy to install and look great on trailer. Low profile and small but very bright LED's. They really look much better than the old bulb type I had on there before. I have not "dunked" them in the salt water yet but hopefully they will hold up.

the submersible LED trailer lights are still shining as bright as ever despite repeated dunking in salt water for the past year. These have been a great purchase.

The hardware was all mismatched. It should have been stainless steel hardware to prevent a bad ground over time. The bolt was a metric grade 5, and the nut was grade 8, the screws that hold the light to the mounting bracket are stainless.

I bought these light for a pull behind motorcycle trailer build I was doing and I am pleased to say they have been great! They have been on the trailer for about a year now and I have travelled with the trailer for about 3500 miles now towing it behind my motorcycle. No problems or issues. They draw very little power which is great for a motorcycle charging system.

I wish they didnt use the cheapest off color mounting nut and lock washer. Would be really smart to just use the right hardware so these self grounding posts dont always rust away. The whole reason im buying one in the first place.

- Upgrading Lights on 2000 Tracker PT175 Trailer to LEDWe do offer a wide variety of replacement lights for trailer but since trailer manufacturers don't keep a record of what they use on trailers I would need some pictures of the lights you are wanting to replace along with some measurements so I can be sure to recommend the correct parts.

- Looking For Replacement Marker Light SAE A PC2 DOT 17 For A 2022 Surveyor LegendHello James. I can definitely point you in the right direction, but the SAE number is not actually a part number, so this is not a good way to look up a specific light. The light in your picture looks very similar to the Optronics LED Side Marker Light # MCL32RBB. This light measures 4" long and 2" wide which is fairly standard for marker lights. If this is not the same size as the light you have, just let me know the dimensions of your light and I am happy to make a recommendation.

The Peterson item # M152A is what you'll need to replace the marker light in your Shorelandr boat trailer's fender. This is an incandescent light that measures 2-1/2" wide x 1-1/4" wide. It is sold individually and has two male terminals that accept a standard 2-wire female plug. I attached a picture below so you can see the terminal connections. I know you said you preferred to avoid an LED replacement light. However, the Thinline LED Clearance and Side...
view full answer... - Replacement LED Trailer Lights for a 2000 Ranger R71 Boat TrailerI would love to help you upgrade to LED lights on your trailer but unfortunately, trailer manufacturers don't just give us a list with every light on the trailer for situations like this. If you can provide me with your full 17 digit VIN I would be more than glad to call on your behalf and see if we have the correct replacements for you.
view full answer... - Will Optronics LED Combination Lights Work ON 2023 Shoreland'r TrailerHey Jeff, welcome back! The Optronics LED Trailer Light Kit # TLL16RK will work well on your ShoreLand'r as long as the size works for your mounting locations. The lights measure 8-1/16" long x 2-7/8" tall x 2-13/16" deep, and they're completely sealed and submersible. For the small amber lights by the wheel wells, I recommend the Optronics LED Clearance Light # MCL95AB. These are also sealed and submersible and measure 2-1/8" x 1-1/8" x 1-1/16". If you were looking for a different size...
view full answer... - Troubleshooting LED Lights on 2008 Shadow Horse TrailerSince most of your trailer lights are functioning I would check the two subject lights' mounting and wiring for the cause for the problem. If the light uses a mounting stud or mounting hardware to establish the ground, like # MCL95AB, then you can try sanding/cleaning the mating surfaces to remove any corrosion, dirt or trapped moisture that could be interfering with the electrical connection. Also inspect the wiring for signs of damage from road debris or hungry critters. Once you have...

This is an LED light which is 2-1/8" long x 1-1/8" wide x 1-1/16" deep and mounts by plated steel stud on base of light. It has gotten close to 200 reviews from our customers who have used it and a nearly 5-star review. I've added a link to a review video of the light for you to take a look at.

Keep in mind you will also need Ring Terminals # 44-5310A and Loom Clamps # A0500 For LED lights I highly recommend checking out the LED Trailer Tail Light # STL57RB (Driver's side) and # STL56RB (Passenger's side). These are submersible lights with a total of 40 diodes and have mounting holes that are 2" center to...

- What Gauge Wire Is On Optronics LED Clearance or Side Marker Light MCL95ABHey Miles, the gauge wire that the Optronics Clearance light part # MCL95AB has is 18 gauge. What gauge wire do you have for this circuit on your trailer?
view full answer... - Troubleshooting Trailer Running Lights Not WorkingThere are a number of potential issues that could be causing your running lights not to work, but you will have to troubleshoot the problem with some detail. The first thing to do is take a look at your vehicle's owner's manual to locate any trailer fuses or relays and ensure they are all there and in working order. If they are, in order to determine the specific problem you will need to purchase a circuit tester if you do not have one - the very handy Cordless Circuit Tester # PTW2979...

view full answer... - Do Trailer Taillight Kits for Over 80 inch Wide Trailers Need Amber LightsHey Darrell, yeah the correct kit for over 80 inch wide trailers that are less than 30 feet you do need to have a coupler amber lights and reflectors up front like what comes with the part # V944 plus a set of amber clearance lights # MCL95AB which is LED like you are wanting. I am not sure why the kit you referenced doesn't have those included but I will send an update to have that changed.
view full answer... - Availability of Amber Version of Optronics Clearance Light OPT53FRHey David, we have an amber version of the # OPT53FR with the part # MCL95AB like you are looking for. This is a single wire design but that means you'd just need to run your ground wire to the mounting hardware of the light and then the power to the power wire of the light.

I took one apart in our warehouse and the bolt looks to be just a zinc coated/plated bolt with a silicon bronze lock washer and nut. For salt water applications grade 316 stainless steel, silicon bronze and aluminum are going to be the most resilient materials. There isn't another clearance light available...

They're still surface mounted lights but the base is included and may work for you. They're also a single wire design so they ground through the mounting hardware. If these will not work for you reply to my email with your pictures and dimensions and I'll see if I can find some that will.

If you also want to replace the lights with LED lights, you will need to swap all lights on the trailer to avoid issues with combining LED and incandescent lights. To replace the tail lights I recommend using the...

- How to Mount Trailer Clearance Lights that Ground Through the Mounting StudsWith a one wire light like the Optronics Mini Rectangular LED Clearance Light, item # MCL95AB, you can ground the light in one of two ways. If the light is mounted to a location that allows for the mounting bolt or screw to contact a good ground location such as the vehicle frame then you can mount the light in this location. Then, run the power wire to a 12 volt positive tail light circuit without further wiring. If the location the light is mounted to is not a good source of ground,...
