Optronics Trailer Lights - STL89RCB

Highlights

  • Bright Light With Less Power: 11 red LEDs output strong stop, turn, and tail signals while drawing only 0.35 A at 12.8 V.
  • Reliable In Any Weather: Sonically sealed, waterproof housing keeps water out for submersible use.
  • Low-Profile Fit: 17" L × 1-3/8" W × 1" D surface-mount design installs flat without cutting holes.
  • One Light, 3 Functions: Provides stop, turn, and tail lighting so you stay visible and compliant.
  • Built To Last: Polycarbonate lens and SMT circuit board resist shock, vibration, and heat.
  • Simple Wiring: 3-wire setup with 16-1/8" hole spacing makes replacement or upgrade straightforward.

Features to know about

Reliable Lighting in All Conditions: Sonically Sealed and Fully Submersible

Wet roads or boat launches are no problem for this light. The housing and lens are sonically sealed together into a single waterproof unit, keeping moisture out and protecting the diodes and circuit board from corrosion. You can count on it to stay bright and functional even after full submersion, making it a dependable choice for trailers exposed to water.

Better Visibility with Low Power Draw: 11 Efficient LEDs

This 17" Streamline LED combination light uses 11 red diodes that deliver strong stop, turn, and tail signals without hogging power. At 12.8V, it draws just 0.35 amps for stop/turn and only 0.022 amps for tail function. The LEDs shine brighter while using less energy than traditional bulbs, so your lighting stays sharp without overloading your system—and there are no fragile filaments or bulbs to replace.

Slim Design That Fits Cleanly: Low-Profile Surface Mount

Measuring 17" long x 1-3/8" wide x 1" thick, this light has a sleek, low-profile shape that mounts flat against the trailer surface. With mounting holes spaced 16-1/8" center to center, installation is straightforward using standard hardware (not included). It provides a clean look with no need to cut holes into the trailer body, making it ideal for streamlined setups.

Surface-mounted Optronics Streamline LED trailer tail light shown installed flat on a trailer surface with flange-style mounting.

Built to Last: Durable Polycarbonate Construction

The clear lens over red LEDs and tough polycarbonate housing handle vibration and shock without issues. Surface-mounted technology (SMT) on the LED circuit board improves heat distribution and adds strength while keeping the profile thin. That means you get a long-lasting light that holds up through years of use out on the road or at the ramp.

Great Experience. You say what you do, and do what you say.
More companies should follow this example.

Installed new LED Tailights on cargo trailer, but unable to try them so far.

I don't expect any issues. Product looks much better made than
original.

I will be back in the future.

THANK YOU



by:

these lights look great on the trailer. I welded a piece of c-channel onto the back of the trailer and set these inside the c-channel for protection from bumping. Looks amazing



by:

My trailer takes a beating year after year. Replaced all my lights on my utility trailer last year. Lights still look new and all work even sitting in extreme weather.



by:

Lights were an exact replacement fit for the factory lights that were not working well. The new lights are brighter and better for safety.



by:

Light em up!!!If you wanna be seen then these are what you need. Beautiful LED's! I also installed the 6 1/2" X 2 1/4" trailer stop/turn/tail lights, from etrailer, and you can see my trailer from Miles away!! I also installed the etrailer clearance lights, red and yellow, 2 1/4" X 1" LED's.
And I have the Firestrip on F-150 King Ranch.
I am quite easy to see with the Awesome lighting products from etrailer!
Shipping is LIGHTning Fast!! etrailer Rocks!

This was replacement for OEM LED lights for a trailer. Items were exact fit for original lights.
etrailer has the most extensive inventory I've found for any trailer item. Great service and fast shipping. Not my first time...I keep coming back.
Thanks etrailer for being there!



by:

Used the lights on a headache rack for extra brake lights. LEDs are bright and look good. I did notice that since there is no bezel for these lights, the clear plastic lets you see the wiring and the surface that the LEDs are mounted on. Not a big deal where I have these mounted but it may be a concern for some.



by:

product is what I am looking having 11 diode is perfect.
Original I went back to trailer company to get lights. which they no longer had.
Back side of light has a recessed pocket that i can cover grounding screw.
this in turn will give me a flushed light on back of trailer, a finished look.
By no means am an expect.
With that you have answered all my questions
Communication is a big help and you are excellent at that
thanks for the help!



by:

I replaced my taillights with the Streamline LED lights and they work very well. All the lights are always on unlike my old ones that I replaced. I'm very happy with these lights.



by:

Great so far one little thing no screws ok



by:

Looks great as a clearance light/center brake light on the rear of my horse trailer.
Just use a current transformer on the trailer brakes' wiring to energize a relay powering the brake function (red wire).



by:

Lights are great. Very !!! Bright
Quick
shipping and great quality.

Lights r just as good as new. Never had any issues would definately purchase again.



by:

We have three of the lights on the back of our 20' cargo trailer. Everyone can see us, see the turn signals, clear night or foggy night. We feel a lot safer on the road with these lights. Thanks, eTrailer for a great product



by:

This is the second order of its kind I have made. etrailer shipped the item in a reasonable time and it is packaged well arriving safe and sound. This is a quality light I would recommend to anyone interested in adding that additional touch with, tail, brake & turn combo. I used mine on the rear of a large fifth wheel RV as a second set of lights up high to be more visible to larger vehicles and at a greater distance. My rig is 13 feet high and factory lights are mounted real low.



by:

Once I got to the wiring of the trailer and made the connection, the Lights are perfect for the trailer.
I will buy from etrailer again when needed.

Been on trailer for the last 11 months and is working great



by:

Great product, perfect replacement easy to install!



by:

Products arrived in great shape and excellent customer service!



by:

Yes, the STL89RCB is impressive especially at night. It was a badly needed upgrade to my existing brake/tail lights which have been partially blocked by new bike rack. I gave it 4 stars since the pigtails from the light were not consistent: on one light, the red wire was the tail/running light but the other used the black wire. Good thing to check both lights before soldering.

The lights worked well for my Casita trailer since i have bikes on the back blocking the primary lights. They are quite visible from other drivers.



by:

Fast shipping, super easy wire for wire replacement and perfect fit.



by:

Put them on the back of my teardrop for added safety. Tricky mount but my neighbor is good at welding aluminum I got at Home Depot.

Thanks



by:

I have been very pleased with etrailer orders recently. Everything shows up when expected and products are as expected. Attached are a couple before and after pictures of my recent project to add lights to a cargo rack per my wife's request. Thanks for the professionalism of all at trailer



by:

Great product. Fast shipping. Works pe rfectly.



by:

My trailer lights developed a short in the right turn signal.
I traced the problem into the wall of the trailer.
So I decided to replace the stop turn signals
These lights are just what I was looking for
Very light weight
Easy three wire set up
There are no instructions
Mine was..
White-ground
Black-tail
Red-stop/turn



by:

The lights were perfect, as advertised, the mounting was exact and installation easy. The product arrived a day early and I would highly recommend etrailer for any of their products. Also the lite bar was exactly the same as the old ones on my cargo trailer.
