Features to know about
Brighter Lighting with Less Power Draw: 22-Diode LED Design
Older incandescent lights can fade or burn out fast, but this 8-function LED tail light steps up the game. It uses 22 diodes that deliver strong, even light for stop, tail, and turn signals while drawing minimal power—only 0.259 amps for stop/turn and 0.062 amps for tail at 12.8 volts. The LEDs last up to 50 times longer than standard bulbs, so you won’t be swapping them out anytime soon. That means bright, reliable lighting every time you hook up.
No More Water Worries: Fully Sealed and Submersible Construction
If your trailer sees water, this light is built to handle it. The circuit board is sealed inside a waterproof housing, keeping moisture from ever reaching the diodes or electronics. Designed for full submersion, it’s ideal for trailers that get backed into the water or see heavy rain and spray. You can count on the light to stay clear and functional instead of fogging up or shorting out after a few launches.
All-in-One Coverage for Trailers Over 80": Eight Functions in One Unit
This rectangular driver-side light covers all eight required functions in a single compact unit—stop, tail, turn, side marker, side reflex reflector, rear clearance, rear reflex reflector, and license plate illumination. Measuring 8-1/16" long x 2-7/8" tall x 2-13/16" deep, it fits neatly on the rear corner of trailers over 80" wide to meet FMVSS 108 and CMVSS 108 lighting standards. The included surface-mount design keeps installation straightforward with a clean look once installed.
Built for Visibility from Every Angle: PC-Rated Beam Pattern
Safety at night means being seen from more than one direction. This light’s PC rating gives it a full 180-degree spread—90 degrees to either side of centerline—so it stands out both straight on and from the side. That wide beam pattern helps drivers spot your trailer sooner in traffic or low-light conditions, reducing close calls when turning or backing up.
Simple Wiring That Just Works: Three-Wire Pigtail Design
Hookup is easy thanks to the clear three-wire setup: white for ground, brown for tail, and green for stop/turn signal. The wires are ready to connect directly into your harness with no guessing which lead does what. Once mounted and wired in, you’ll have a dependable LED system that’s rugged enough for real-world use every day.

I called up Etrailer.com and was assisted by a very friendly and knowledgable young lady that helped me get exactly what I needed. The transaction was as painless as possible and took all of about 5 minutes. I had already found the left LED light part number and she told me the part number for the right side light, both matched up exactly to the shape/size and mounting configuration of my existing light that had bulbs.
My package arrived in great shape in only 2 days and installation was a breeze - around 5 minutes a light. The LEDs look great and gave my 4 year old boat trailer a new look. I highly recommend etrailer for any lighting needs you may have and also the LED lights. No more bulbs to blow out and no more worries of corrosion of the fixtures.

I have been dunking these lights in salt water every weekend for more than a year on my boat trailer. Gone are the days of chasing corroded bulbs and sockets. Remember to use heat shrink on the electrical connections to keep them waterproof.
On top of that, these lights are nice and bright.

These lights continue to take dunking in salt water. It feels great to know that each trip doesnt start with an effortto find that burned out bulb or corroded connection. Be sure to use shrink tubing on the wire connections, though.

This light was a much needed upgrade on my boat trailer to make it look more modern and not so old. It is very bright, fit right into the existing holes I used for the old lights and wiring it up could be easier! Have yet to dunk it in the water but I'm sure it will be just fine! Great Product!

I needed to replace some of the lights on my boat trailer. The old light were incandescent and some of the bulbs had burned out, securing screws were rusted. Product was exactly what I was looking for. Links on each product web page provided very good description and product information.
Thank you for great selection and process.

smoothly, especially since it was my first time to the website. I was amazed at the vast amount of inventory at etrailer and decided I will be back. Tracking of my order was easier since the tracking info was preset into the url as opposed to being directed to a general site. Delivery was in the allotted timeframe. My thanks go out to Herb for securing the 3-5 day express shipping. Thanks etrailer.

Purchased a set of these lights as replacement/upgrades on my existing standard boat trailer lights. These LEDs lights perform exactly as described. They are completely water tight. After one full year of use, they perform as well as the day I installed them.

Replaced broken tail light on a 2003 520 very Ranger boat trailer. I changed over both lights as I am not interested in spending $170 on not exact replacements. These lights work great. Wiring diagram would help. Not a big deal. If you get wires crossed up, it is obvious that reversing connection is needed. I ordered stl 16 and 17.

Flawless throughout the year bouncing along the highway and loading and unloading my boat in frigid water. Twice as bright as my previous "sealed capsule" tail lights, which I would have had to replace 2-3 times in that period.
Wish I had found them years ago!

etrailer.com has turned out to be a great resource for all my trailer parts. I found them by accident after I got my first trailer. I recently bought a pair of LED Tail lights and they were shipped within hours of getting my order. They were a direct bolt-on. Couldn't have been easier to replace.
etrailer.com is my new favorite for all my trailer parts going forward.

These are excellent lights, very bright. an exact replacement for my existing lights that had begun to leak a little around the seals. These were easy to put on. I used crimp wire splices to attached the wires then put heat shrink tubing on them to seal. I don't submerge often so we'll see if i have any problems with this attachment. etrailer shipped promptly as always.

Factory wire leads need to be a little longer and ground wire needs to have a ring terminal with an integral heat shrink wrap. The open crimped ring terminal with exposed wire provided on this light will quickly corrode and fall apart on a boat trailer when exposed to salt water immersion. Otherwise, a good quality LED light.

This was a replacement for a damaged tail light on my boat trailer. Great tail light, clarity of the tail light is amazing and it's waterproof! Ordering was a breeze, shipping took a little longer than I expected, i.e. 7 days. But, I was provided with a tracking status once the order was processed.
Thank you!

One of the encased waterproof housed bulbs was shot on my trailer, and it was the style where I had to buy the entire unit.. So at that point, I figured I might as well replace both with new LED models. These are bright and amazing, I love them.
The etrailer person in the forum posted exactly what I needed, shipping was quick, and installation was a breeze.

Bought this to replace a tail light on my boat trailer that had lost its seal and was not working. The new light arrived in good condition, fit properly, was easy to install, and has worked well for the past year.

For the Optronics # STL17RB and # STL16RB tail lights 16 gauge wire is what I would use. For the brakes you will want to use at least 12 gauge wire. If it is a shorter trailer you can get away with 12 gauge, for longer trailers say 20' or longer you may want to up that to 10-gauge. We sell this wire by the foot if you need some.
