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.
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.
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.
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.
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.

Light up nice at night
Product arrived well packaged and on time. Used them to light up my running boards on a Ram 3500 (went a little retro) Ran these to my 4 pin trailer Harness and they work great. Love the look. Have already recommended to someone else that liked mine. Would order again.
My initial thoughts are the lights seem well-made. They are very brighten once I’ve installed them very happy with the purchase.
Worked as it should
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.
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.
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.

As of the last time I launched which was in November the lights still worked great. They have been fully submersed many times in either fresh or salt water.
Great product so far, bright and matches existing truck Amber LED lights. Easy to install with stud attached and single wire.

Product still works with no problem. Recommended for any use.
Found the exact lights on my 13 year old boat trailer for a perfect match. Quick shiped
The wires were so thin, that even at the smallest setting on my wire stripper, half of the actual wire itself came off with the shielding. I bought others and threw these away
Timely shipment of the exact items I viewed online and needed to repair my boat trailer. I will go back to etrailer when I need items in the future. Price was also fair. Thanks etrailer.

Lights have worked well with a year in service. I would buy them again based on fit, price and reliability.
Perfect match. Received in a timely manner. Would recommend e trailer!
Excellent company to get all my supplies for my boat trailer thank you Bill
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.
These are the perfect size to replace damaged markers on my cargo trailer. They are very bright and hopefully will last as long as the previous ones on there.
Great price. Product was exactly as described. Good quality and waterproof.
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.
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.
The clearance lights were just what I was needing very pleased
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.

At first the light was brighter than the other lites on the trailer. It has settled down so as to match the brightness of the other lights.
Had trouble tracking these specific lights down online. I have bought a few things from etrailer before and they always deliver exactly as advertised. These are a direct replacement for the lights that I had which seemed impossible to find!
These Optronic LED lites were exactly what I was looking for my boat trailer. Easy install and very bright. Good product and quick shipping. I highly recommend this company.

That's great to hear, Jim! I'm glad to hear your marker lights are working well for you. Where's your favorite boating spot? I really like Table Rock Lake in Missouri near Branson...

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.
