Old bulbs can fade or burn out when you need them most. This 5-3/4" round Optronics LED trailer light uses 10 clear LEDs behind a red lens to deliver bright, even output for brake, tail, and turn signals. It glows steadily for tail light mode, brightens for braking, and flashes clearly for turns. With only 0.413 amps at 12.8V on stop and 0.026 amps on tail, it draws very little power while running cool and lasting far longer than incandescent bulbs. The built-in reflex reflector adds extra visibility without needing a separate reflector piece.
Water is the enemy of most lights, but this one is built to take it. The polycarbonate lens and housing are sealed to keep moisture out, making it waterproof and great for boat trailers or wet environments. Even though the back of the light is exposed, the circuitry and diodes themselves are sealed to prevent shorts or corrosion. Add a bit of dielectric grease on the plug pins, and you’ll keep water from sneaking in around the connection too.
No need for brackets or complicated wiring. The light mounts directly using its built-in flange—just cut a hole right around 4-7/8" in diameter and secure it in place. The overall diameter is 5-3/4" with a thickness of 1-5/8", giving it a clean surface-mount look once installed. It works with standard 3-prong PL-3 connectors, so you can plug in straight with the A45PB pigtail or use the A47PB right-angle pigtail if space is tight.
Upgrading to LEDs isn’t just about brightness—it’s about efficiency. At only fractions of an amp per function, this light helps reduce electrical load while keeping full luminance even on long tows or smaller wiring setups. The durable LED design means no bulbs to replace and a lifetime warranty on the diodes, so once it’s mounted, you can rely on it trip after trip without worrying about maintenance.

I could not immediately find the part online and I had to ask a bus repair facility to find your website. Once I found your website, it was a breeze to find the right part and to place an order. The website is very well constructed and it was very easy to use.
Thank you for the great and timely service.
Took old one out. This one for in with no adjustments needed. Works great.
Fast delivery. Works like new.
Worked perfectly! Thank you :)

The light assembly is still working great!
Love the shipping communication!
Exactly what I needed. Worked perfect and will brighten up my trailer to be seen at a good distance.Thanks
fast great service upgraded shipping for free without even asking.excellent product
Very good service, Fast shipping
great experience with etrailer for first time customer.
Exactly what was needed for a very good price. Easy to install. Good seal to prevent water entering. As usual, etrailer.com solved the problem.
Spent over 8 hours looking for these same exact lights before I put my bus on the road for inauguration. Went to dozens of bus dealers, and part vendors, but i couldn't even find similar. Even called the manufacture, but they advised since i wasn't a distributor, they couldn't sell to me directly, neither did any of there distributors have it. Make a long story short, etrailer saved my butt!
Reasonably priced . After having them on for one year no problems. An led tailight will at 65 miles per hr illuminate an average of a car behind you seeing them come on 50feet sooner.
I found the web site easy to navigate and had the EXACT light I needed.
The cost was quite reasonable, and shipping was quick.
Thanks.
I WILL be ordering more, now.
We’re upgrading a 1960 camper with LED lights throughout. These work wonderfully and are very easy to see. Good price, great service and product, highly
recommended.
Product easy to find on website. Reasonably priced and shipped as promised.
I purchase all Optronics lamps from ETrailer.
Only problem is this product is under the 4" lamps and outside diameter is actually 5 3/4". But was still easy to find.
Great customer service when and if you need to call them.
Mid-understood flange. Had to cut fiberglass. No big thing. Also needed to purchase electrical connectors. Would have helped if more needed info was addressed
Have found and purchased some of those hard to find items through etrailer. Found this LED tail light for my Newmar RV. Exact replacement. Delivery on time and no issues, will continue to purchase again from etrailer
I bought this for my Newmar motorhome. It was a perfect fit for the old light that had only a couple of LEDs still working. It has been working flawlessly for a year now and still looks new. Highly recommended.

Still working great after two years.
I have a 2008 Discover America 5th wheel. One of the led tail lights had several burned out LEDs. This replacement worked perfect although the light pattern is slightly different.
Direct replacement for one exactly like it Same brand and all, although the original lost a few LED's It makes me wonder how good these lights really are..

I am unsure if your trailer used Optronics Brand LED Puck lights, but one thing is for sure these lights have a lifetime warranty for LEDS!
Very bright & well made, I replaced these on my class A RV, the OEM manufacturer used them on the original build in 2014, replaced with a new set in 2020 and couldn't be happier knowing every thing behind me on the road sees me stopping, turning, whatever... Very good - quality product! Highly recommended. To be clear, I purchased these myself at full price from eTrailer!

Update after 12months of use: Product still working as well as they were from day 1, still highly recommended...
One piece, easy installation. Worked like a charm!
I have a Newmar coach which I had a LED taillight that burnt out. I called Newmar and checked several other suppliers but no one had the one I needed. I then logged on to etrailer.com, found the exact match, ordered and received it. I’ve used etrailer in the past for towing related items but they will be my first shopping stop for all my RV needs.
Perfect fit and these lights came with rubber gaskets which the factory lights to my surprise did not!
updated our motorhome from the old square type with bulbs to these round type led lights and could not be happier..bright and a more modern look...highly recommended
