Tired of dim or unreliable plate lights? This 3/4" round Optronics LED license plate light uses two white diodes behind a clear polycarbonate lens to cast a clean, bright beam with minimal power draw. At just 0.03 amps when running at 12.8 volts, it’s easy on your electrical system while putting out solid, even light that keeps your plate clearly visible and compliant.
If your trailer sees wet roads or launches into the water, this light is built to handle it. The circuit board and housing are completely sealed to keep moisture out, making it fully submersible. You won’t have to worry about corrosion or failure from water intrusion—the waterproof design protects the LEDs and circuitry so they keep shining season after season.
Forget swapping burnt bulbs or dealing with fragile filaments. The solid-state LEDs in this light last up to 50 times longer than standard incandescent options. They’re more efficient too, producing brighter output with less energy use, and there are no bulbs to replace—just dependable performance every time you hook up.
Space can be limited on some trailers, and that’s where this compact design helps. The 3/4" diameter round housing tucks neatly into place using a recessed mount setup. It connects with a simple two-wire pigtail featuring 0.108" female barrel connectors, making wiring quick and straightforward with minimal tools needed.
When properly mounted using the optional A11GLPB bracket (sold separately), this light meets SAE J587 requirements for license plate illumination and is DOT compliant. That means it not only looks clean but also meets legal lighting standards—giving you one less thing to worry about when you’re towing or hauling after dark.

Today we're going to be taking a look at the Optronics LED trailer license plate light. This is a compact light that illuminates your trailer's license plate when mounted with the required bracket. It meets SAEJ587 standards when properly mounted using the mounting bracket. That is sold separately with part number A11GLPB. You can find it right here at etrailer.com. This is a sealed waterproof construction, so it is submersible.
It's going to contain 2 LEDs. LEDs make great replacements for incandescent lights. They last longer. They burn brighter. They're much more efficient.
You don't have to worry about replacing bulbs or brittle filaments. It's going to be a polycarbonate lens. It's very strong and durable. The LEDs are going to be white LEDs. It's got the 2-wire pigtail with a nice wire casing around the wires to keep it protected. You're going to have your white wire and your black wire.
White's ground. Black is power. It's going to have the 0.108 female barrels on here for a quick connect design. Those can be cut off. If you want to hard wire this, you just cut those off, strip back the wiring, and you can use it for a hard wire application. That wire harness measuring from the back of the light housing to the closest point of the connectors is about 7 inches long.
The unit is department of transportation compliant. If we took a look at the diameter of just the light it's going to measure about 3/4 of an inch in diameter as you can see there. Again, it's got two LEDs. The power draw at 12.8 volts is 0.03 amps. Optronics puts a lifetime warranty on the LEDS. We're going to go ahead and hook it up to an external power source. That way we can see what it looks like with power running to it. We'll turn off our overhead lights so you can get a good look at how bright the light is. You can see here that it sends out a really nice, clear, consistent signal. Two diodes, so the multi-diode design really helps increase the light output. It also provides that nice, consistent signal that we're looking for. The white LEDs with the clear lens allows plenty of light to come through. Again, this is designed to be mounted with the required mounting bracket for a license plate light. That is sold separately. Again, you can find that bracket on our website with part number A11GLPB. That's going to do it for today's look at the Optronics LED trailer license plate light.

Ratings & Reviews
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
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.
Great job
Nice piece. Makes my plate legal and legible.
Everything arrived when I needed,how I needed, will be ordering again soon!!!
Just what I needed
works good
No problem with the light
Good light output, exactly what I expected. Fits where I need them too and seem well made. Very satisfied.
PRODUCT WAS AS ADVERTISED AND WORKED FOR WHAT WE NEEDED OTHER THAN A SMALL SHIPPING MISS-HAP THAT WAS ADDRESSED IMMEDIATELY, EVERYTHING WENT WELL WILL BUY AGAIN FROM COMPANY
Got my lights in a timely manner and it was just what I needed for my project!
Content, price, and deliver best around. Excellent. Will be back!
Tag light arrived as promised and appears to be very good quality
The second part of my customers order, just what I needed, works fabulously.
I received this license plate light right on time
Great company to deal with
real nice little LED light. Needed to order the mounting base for it however. This is a real BRIGHT light. If you get one, don't forget the base.
Worked well using the ear mounting bracket for Optronics. The bracket and the LED light should be sold as a set.
everything I ordered was well packaged and the video's help me pick the exact lighting I wanted. Five stars on all the items and five stars for etrailer
Nicely made but it looks like a marker light, it doesn't shine light on the plate / in the direction it's pointing.
I am very happy with the great support from etrailer, they helped me build a beautiful trailer.
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!
