This 4-5/16" round Optronics LED trailer light brings a major upgrade from old incandescent designs. With 21 diodes behind a red lens, it delivers a crisp glow for tail lights and bright, instant illumination for brake and turn signals. At 12.8V, it draws only 0.208 amps on stop/turn and just 0.013 amps on tail light mode, keeping your electrical load low while improving visibility day or night. The LEDs are built for efficiency and come backed by a lifetime warranty, so you can count on them for the long haul.
When your trailer sees rain, road spray, or even the boat ramp, this light doesn’t flinch. The polycarbonate lens and housing are sonically sealed to make the unit fully waterproof. It’s designed to handle submersion without letting moisture in, keeping the electronics safe from corrosion or failure. That’s peace of mind every time your trailer hits wet roads or backs into the water.
Swapping out old lights shouldn’t mean rewiring your trailer. This light uses a standard PL-3 connector that works with common 3-prong plugs like pigtail A45PB or A47PB (sold separately). Just plug in and go—no complex wiring or adapters needed. It’s an easy fix when replacing worn-out OEM lights or upgrading to LED performance.
If you want a clean, built-in look, this light recesses neatly into your trailer body using grommet A45GB (sold separately). The fit is snug and secure with a finished appearance that protects the lens edges from bumps and snags. Prefer not to cut a hole? You can install it using the BK45BB mounting bracket (sold separately) for surface mounting while still using the same grommet. Either way, setup stays straightforward and professional-looking.
Every part of this light is designed for life on the road—or off it. The one-piece polycarbonate housing and lens resist impact, vibration, and weathering so you won’t be replacing cracked lenses or chasing down shorts from moisture intrusion. Once installed, it just works—bright, efficient, and tough enough to handle years of use.

Great product fit exact into existing g asket
Would be 5 stars except that they were hard to install in the grommets. Finally had to grind the ridge off to get them to fit into the grommets... Great once installed!
Was very pleased,I also need the trim to cover the screws on rail on the side of my trailer
I am very pleased with product and extremely satisfied with prompt service and shipping and I will definitely buy from e trailer in future Thanks
I’m so happy I was able to find the trailer light that fit perfectly on my 1977 holiday rambler. Thank you so much
Fit perfect easy to install replaced 20 year old trailer lights LED. BIG Difference!
Quality LED lights with pigtails! Fit great and works well.
Correct light to replace my trailer lights. Great product
good product, looks nice lit and easy to install, oredered on Sunday received on Friday. Took me approx. 1 hour to install all 15 lights on my dump trailer.
I got 2 of these jewels for my trailer lights. They are very bright and look great. I plan on ordering 2 more.
Better than the original
We replaced all 4 tail lights on our 5th wheel trailer with LED lights. They were easy to replace and work great.
Best lights for boat trailer that I have found. Even with frequent submersing last around 5 years.
The product arrived quickly and was just as described. My trailer is older and I was having trouble finding replacements for the tail lights. Their sales rep, Cathy T., was knowledgeable and friendly. The next time I need parts for my horse trailer, I will go directly to etrailer.
This light fit into my new used truck camper like a pro. etrailer.com has all my future business of this sorts. The product was accurately described and the website is as easy to navigate as any I can think of.
The lights are bright and easily seen. A wiring harness is not included and I had to order independently. Also, no screw to secure the ground wire. I was able to adapt these lights to an old trailer with different trailer light housings fairly easy.
received the lights in perfect condition and extremely quick. they are perfect for my new tail lights which will be mounted to a piston for my rat rad truck.

Excellent
Product was exactly what I was looking for as I was replacing a 4" taillight on a truck camper. Since the 4" lights are fairly standard, I was able to quickly replace the bad ones. Staff went out of their way to offer me a more effective shipping solution that what I had chosen on my own including taking the time to personally contact me. My first purchase with them, very satisfied.
So bright and noticeable nobody will come close to my rear bumper
These are fantastic. I really like the brightness, how they install (quick connector plug) and the fact that they are sealed. They mount in gasket that also provides shock protection and a good tight fitting. Had no issues with either one to date. Would buy these for all future trailers. Looks great, works great.
Easy to install and was an exact match to my trailer original equipment. This light has triple the LEDs in it so the lighting to the rear of the trailer is much brighter and safer.

Very impressed. Everyone commented on the brightness of the led brake lights. If needed, I would purchase again.
I had to replace one of the lights on my
trailer and I ordered a spare while I was at it. Exact same led that matches the other lights. Looks great.
