Features to know about

Brighter, Longer-Lasting, and Efficient: 11-Diode LED Tail Light

This Thinline LED tail light gives you the brightness of modern LEDs with far less power draw. It uses 11 diodes to deliver clear stop, turn, and tail signals while only drawing 0.350 amps on stop and 0.022 amps on tail at 12.8V. The red lens sits over white LEDs for a crisp, even glow. With LEDs that last 50 times longer than old incandescent bulbs, there’s no filament to break and no bulb to swap out—just reliable light every time you hit the brakes.

Tight Spaces Made Easy: Low-Profile Thinline Design

When space is limited or you want a cleaner look, the Thinline Series low-profile housing fits the bill. Measuring only 15" long x 1-3/8" tall x 5/8" deep, this light stays streamlined against the surface. The mounting holes are set 14-1/8" center to center for straightforward alignment. It surface mounts without sticking out awkwardly, keeping things neat and out of harm’s way.

Built to Handle the Water: Sonically Sealed, Submersible Construction

You don’t have to worry about moisture getting inside. The housing and lens are sonically sealed into a single waterproof unit that’s fully submersible. Whether it’s rain, road spray, or boat ramp dunking, water can’t sneak in to corrode the circuits or damage the LEDs. That means long-term reliability in every environment.

Simple Hookup That Just Works: 3-Wire Hardwire Design

Wiring is straightforward with the 3-wire setup—each wire dedicated to its own function for stop, tail, and turn signals. It connects directly to a standard 12V DC system so you can wire it up quickly without guesswork. Once installed, it’s DOT compliant and ready to perform right away.

Durable Build for Everyday Use: Polycarbonate Lens and Housing

The tough polycarbonate housing and lens hold up under vibration and weather exposure. This sturdy construction keeps the light clear and functional through constant towing, travel, and use. It’s built for long life so you can trust it mile after mile.

High quality as I expected. Very pleased



by:

They are a perfect fit for my trailer. Shipping was quick. Not the first time I have bought lights from here. I highly recommend this site for all your trailer needs,



by:

Taillight continues to function(1 year). Unlike the first time I replaced it which only lasted 3 months. It was nice to get the correct replacement light for my trailer. That’s for the quick shipping.



by:

This Led light as worked as well as the original light that it replaced.The light fit in the recession area that the original light and matched the other tree LED rear tail lights.



by:

I purchased this tail light for my 2014 HR Motor Home left turn signal about a year ago. It was a perfect fit and has worked flawlessly since I installed it. I had replaced the right turn signal in 2015 because the OEM light had accumulated water inside the light which made some LED’s to fail and I replaced it with this same light and works yet today as designed.



by:

The lights are still working well. The installation was a bit of a bother because there were 4 wires on the original, 3 on the replacement. After some rewiring, it worked fine.
It required a little cutting away of the RV wall to allow a small part of the back of the light to go through so the light was flush with the wall, but it wasn't that hard.
The lights are bright and add a bit of safety to driving the RV in the dark.



by:

Haven't installed yet but look ok. The lights a made long, slim, & narrow which is what I need for my enclosed trailer.

Working great, just what I needed on car hauler and was a easy install. Thanks !



by:

The light fit and works perfectly



by:

Almost perfect for replacement of original equipment light witch cracked and shorted out the rest of the lights and functions of that lamp. Only problem was it just a bit to short of the original. Easy fix so not really much of a problem, that's the only reason it didn't get 5stars

Still working great !

Haven't had a chance to use the product (xmas present), but the Customer Service was excellent. I was notified immediately when the equipment was shipped, and was alerted that it was expedited even though I only selected Standard Delivery.

I am really glad that this was so easy. I will definitely come back for future Trailer-related purchases.

by:

Super easy installation. Did some quick wiring and the LED s lit up light a torch on my madramps. Super Fast shipping, by etrailer.



by:

Great parts, great price!!!



by:

Very quick delivery and just what was needed. Thanks.



by:

The door mounted lights on my car hauler were crap from day one. With the wires cut off by the door closing on them, it was time to make an improvement and get them moved to someplace other than the door.

The STL69RB lights were the perfect product. Slim enough to mount beside the drop down ramp door and very easy to install. Using 2 per side it made the trailer visable to all vehicles.

The LED lights are brighter and instantly on so drivers behind you imediately know when you are slowing or turning. These are what should have been installed on the trailer at the factory.

They are the best improvement I could ever make to my trailer's rear lighting.



by:

These 11-LED lights were installed on the rear hat deck of my Lincoln MKZ for use when the auto is being towed behind my motor home. These photos were made in bright sunlight and the LED lights show up well both day and night. They are installed using self-stick strips of Velcro. Four 18-ga electric wires in wire loom were run from front bumper, under inside carpet, and into trunk area. Small holes were drilled in each side of a plastic cover over the Lincoln center stop light for the wire to each of the LED light strips.



by:

I’m very impressed with them. Very easy to install



by:

This light is an exact replacement for my existing trailer taillight. etrailer had the best total price (light + shipping). etrailer always has a great inventory and fast delivery. I have purchased from etrailer multiple times and have never been disappointed.

See what our Experts say about this Optronics Trailer Lights

  • Installation of Trailer Lights with Red, Black, and White Wires to Traditional Trailer Wire Colors
    Red, black, and white wires are common on many tail light assemblies. When this is the case, you will have red as stop and turn, black as running light, and white as ground. So you will connect yellow to red on one side of the trailer and green to red on the other side. Then on each side you will connect white to your frame or mounting hardware, and brown to black for your running lights. I've attached a video of similar lights # STL69RB to assist. If you need additional wire, use #...

  • Do You Have a Replacement for a Triple Vision C-82 Rear Camera?
    Hey Sabrina. I am sorry but we do not have a replacement for your Triple Vision C-82 rear camera. That's not a brand we've ever carried. I checked with our vendors and none of their cameras are compatible either. The only option I have for you is to upgrade to the Furrion Vision S+ Wireless RV Backup System item # FR57AD if you're only interested in a backup camera. Or item # FR74AD if you want to add side cameras. How long have you had your motorhome?

  • Replacement Third Brake Light for a 2007 Tiffin Allegro
    Hey Sabrina! I checked with our vendors and we do not have a third brake light that would be an exact replacement for the one currently on your 2007 Tiffin Allegro. The closest option we have is the Thinline LED Trailer Tail Light item # STL69RB. This one measures 15" long x 1-3/8" tall x 5/8" deep. The mounting holes are 14-1/8" apart. The Thinline LED Trailer Tail Light item # STL69RB is going to be a great upgrade though. It's an LED light so it's going to last quite a bit longer and...

  • Could the Optronics Trailer Light # STL69RB Be Used as a Third Brake Light on a Trailer
    The brake output circuit of your vehicle/trailer wiring wouldn't be an ideal circuit to power the third brake light of a trailer unless you wanted to modify the circuit on your tow vehicle. You would have to run a brake light circuit straight to the brake output circuit so that the pin sees 12 volts when the brake are applied. Trying to run the output from a brake controller to a third brake light wouldn't be a feasible option. A brake controller won't send a full 12 volts to the output...

  • Differences Between Optronics # STL69RRXB and # STL69RB LED Stop/Turn/Tail Lights
    The only difference between the two is the height of the lamp. The Optronics # STL69RRXB is 15 inches long by 1-5/8 inches tall, while the # STL69RB is 15 inches long by 1-3/8 inches tall, a 1/4 inch difference. Other than that, both lamps are pretty much identical.

  • Differences Between the Optronics LED Stop/Turn/Tail Light Part STL69RRXB and Part STL69RB
    The difference between the Optronics LED stop/turn/tail light # STL69RRXB and the Optronics LED stop/turn/tail light # STL69RB is # STL69RRXB will have an integrated red reflector to fulfill the rear reflex requirement. If you choose to go with # STL69RB, then you will need to add 2 red reflectors to the back of your trailer to meet federal lighting requirements. I recommend going with the # STL69RRXB because it's not much more in cost and you will not need any additional parts. I included...

  • Installation Of 3 Wire LED Marker Lights
    We don't carry lights with those colors, so you will need to test them based on function. Normally black and red are power and white is ground like you see in the # STL69RB. I would try the yellow as ground. Red is most likely the turn signal and brake function and black is most likely the constant running light.

  • Troubleshooting Thinline LED Trailer Light that Was Partially Lighting and Then Stopped
    Check the connection the wires of the ThinLine LED part # STL69RB are making to your trailer wiring. It sounds like the running light circuit isn't making a solid connection. If the wiring is good though it would be time to replace the light since that would indicate the light is damaged.

  • Trailer Led Strip Light Wiring For Brake and Tail Light
    On your new lights 3 wire LED bar you will likely connect the brown wire to black, the green wire to red, and the white wire to ground on your trailer frame. On your current wiring, the brown is likely the running light circuit and the green is your turn/brake light. The ground is in the mounting hardware to your trailer frame. You can use a circuit tester like # PTW2993 to ensure this is the wiring for your trailer. If you need more assistance you can use the attached help article...

  • Can a Third Brake Light and Running be Added to a 2006 Toyota Tacoma 4x4 Double Cab
    In order to get a light like # STL69RB, to function as a third brake light and running light, you will have to tap into specific wires on the truck. For the running light function, you can tap into any wire that carries the running light function and attach it to the black wire on this light. But the stop light is going to be a little trickier. You do not want to tap into the 4-Way trailer wiring because that would cause the light to blink with a turn signal. What you need is the center...

  • Troubleshooting LED Trailer Lights Not Functioning Correctly
    The Thinline LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 11 Diodes - Red Lens # STL69RB sounds like the ground wire is not connected to a clean connection. It should be bare metal to metal and free of corrosion or debris. If your clearance lights are blinking, it is most definitely a ground issue and maybe your main trailer ground needs to be looked at as well.

    The Sealed, Thin Line, Over 80" LED Trailer Stop/Turn/Tail Light, 3-Function, 11 Diode # STL69RB has had great reviews with our customers. You can test the light by simply connecting that brake wire to a 12V power. This will let you know if the light is bad or if the wiring is bad leading up to it. Most of the time when a single function isn't working correctly it is due to a poor ground wire connection. I recommend making sure your ground wire connection is bare metal to metal and...
