This 3/4" round light uses two white LEDs that shine bright while drawing just 0.03 amps at 12.8 volts. Compared to older incandescent lights, these LEDs last up to 50 times longer and run cooler with less power draw. That means clear, even illumination on your license plate without putting extra load on your wiring or battery.
Water is no match for this light. The circuit board and housing are completely sealed, keeping moisture out so the diodes stay protected and reliable. Whether you’re driving through rain or dunking a trailer at the ramp, this waterproof design won’t short out or fog up, making it perfect for trailers that see harsh conditions.
Installation is straightforward with the built-in pigtail that’s ready to plug into your existing wiring. The two-wire setup keeps things simple—just connect power and ground using the 0.108" male barrel connectors. No extra adapters or complicated rewiring needed, so you can get it mounted and lit in minutes.
Space is often limited near a trailer’s license plate area, and this compact design fits right in without getting in the way. At only 3/4" in diameter, it mounts neatly using a required bracket (sold separately) and gives a clean, professional look once installed. Even small trailers can benefit from bright, compliant lighting without bulky housings sticking out.
Good visibility isn’t just convenience—it’s required for safety. When properly mounted with the bracket, this light meets SAE J587 requirements and is fully DOT compliant. That means dependable performance that meets recognized standards every time you tow.

Hi, everybody, Andy here with etrailer.com. And today, we're gonna take a look at this submersible LED trailer license plate light. Now, this three quarter-inch diameter round waterproof trailer light illuminates your license plate when mounted with the required bracket. And I do have this connected to 12-volt power, and lemme just give you a brief demonstration of what this looks like lit up. The LEDs, of course, make great replacement for incandescent lights. They last 50 times longer and they're more efficient and they provide brighter light with less power output.
So, there's no bulbs to replace and no brittle filaments. And again, you can see this nice, bright, white light that it casts. And this is with my studio lights off and even with my studio lights on, you can see it real well and see just how bright it is. The two white LEDs are behind a clear polycarbonate lens and sealed in a waterproof construction that's submersible. And this is a two-wire pigtail with 0.108 male barrels, as you see here.
And again, this is DOT compliant. And again, the diameter is three quarters of an inch. The power draw at 12.8 volts is gonna be 0.03 amps. And there is a lifetime warranty on the LEDs. Well, that's gonna conclude our brief look today.
I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
Ratings & Reviews
I love the products but the quality of the packaging was horrendous. When I opens the box up there wasn’t enough packing paper in the box to keep the lights from shifting in the box. Most of the lights were out of the low quality unsealed plastic bags and were a scratched and marked up. Along with that there weren’t any bags for the smaller 3/4”lights and were loosely thrown in the bottom of the box with the grommets not being attached in any way. After I pulled the contents out of the box I realized that there weren’t even enough crappy plastic unsealed bags for all of the main 4”and 6” S/T/T/B lights and to finish it off all the electric grease that was in the plugs was not covered in any way leaving all the bags and contents of the box completely covered in di-electric grease. Overall after cleaning all the lights up the products are amazing except for it took a little research to find out that the 4” STTB lights aren’t supplied with pigtails. I’m disappointed of the quality control for your company for the price that you ask.
Works perfectly. Easy to install. Solved the problem of lighting my trailer license plate. Looks great on my trailer.
Item arrived just as stated and work as should be all good
It’s great super brite works as it shou ld
Seems to be a good product, fit fine and very bright.
working on mounting the light.
Ad ordered as expected.
Great little light.
This product solved my need perfectly. All other license plate lights of this style that I've seen only have one wire and ground through the housing. This was not suitable in my case where my light snapped into a plastic housing around the license plate opening. This was the only lamp of this style I found that had a ground wire, which is exactly what I needed. I'm glad I found it and was able to plug the hole in my license plate housing where the original light had gone missing.
Looks good and appears to be plenty bright in the daylight.
Works and fits great.
Thank you very much for the fast shipping and the reasonable prices.
The led lights at etrailer are the best you want quality that's were to go. I've bought others rset at others retailer they dont stand up to one I bought from etrailer.
Thanks
Exactly as advertized! The trailer is off for painting right now, will follow up once it is back and the light is installed.
great lense. I painted the back to get it to shine better on the plate.
Even though the item was out of stock and had to be ordered I do not blame the company for the delays involved after placing my order, especially pre Christmas time with the post office crunch for all retail sales.
However, I have no complaint about the excellent service and communication I've received from etrailer.com. They stayed on top of my inquiries and kept me informed throughout the order process. I was trying to find an exact match for a license plate light/lamp for a Motorcycle Cargo Camping Trailer that was over 30 years old and they were the only ones who had it available after searching thoroughly for it high and low. I would definitely buy from this website again. After doing business with them they have gained my trust and respect. It's the people who stand behind their word and follow through that makes a company great. I truly appreciate their greatness.
The light works perfectly. It's bright enough to light up the license plate from a few inches from the side. The light is wired in place of the existing light and mounted in a new location. It has been in place for a year, many miles, rain, snow and lots of sun. The night time pic makes the light itself look super bright but that is the camera.
Fast shipping and the description was g ood
I added this as a tag light in the center of my tail/brake light. This light is very bright and works great. Thank you Amy and etrailer for your excellent parts selection and customer service!
Perfect replacement for the old incandescent license plate lights on my 2019 Newmar Mountain Aire. I did paint one side silver to match old lights. These new LEDs lights are sealed so I expect they won’t burn out easily like the old lights.
Could not believe the expediate service we received. Would definately order from this company again, easy to do business with
Nice and bright PERFECT thanks
Found this part online to replace a burnt-out light on a trailer. Local parts store was going to charge me over $50. Ordered part and they shipped the same day. Excellent job on keeping me updated on status of order!
Waterproof and bright, great for my application. Fast shipping as always.
