Features to know about

Brighter Light, Less Power Draw: 11-Diode LED Efficiency

If you’re ready to ditch dim bulbs and constant replacements, this thin LED tail light makes it easy. It uses 11 red LEDs beneath a clear lens to handle stop, turn, and tail functions with brighter output and far less power. At 12.8V, it only draws 0.012 amps, so it’s efficient and doesn’t strain your wiring. Plus, there are no filaments to burn out—just long-lasting LEDs that keep working season after season.

Confident Performance in Wet Conditions: Fully Submersible Design

Nothing ruins a light faster than water sneaking inside. The housing and lens on this model are sonically sealed into one waterproof unit, making it completely submersible. Whether it’s heavy rain, road spray, or launching at the ramp, moisture stays out and your LEDs stay safe and bright.

Clean Install Without Cutting: Simple Surface Mount Setup

You don’t need to carve holes into the trailer wall to mount this light. It installs flat against the surface using a flange or bracket—just line up the 14-1/2" center-to-center holes and secure it with your own hardware. The 3-wire design keeps wiring straightforward: red for stop/turn, black for running lights, and white for ground.

Optronics ThinLine LED trailer tail light with clear lens showing low-profile surface-mount design for stop, turn, and tail functions on trailers over 80 inches wide.

Slim Profile for Tight Spots: Low-Profile Build That Looks Good

Measuring 16" long x 1-5/16" tall x 11/16" deep, this light sits close to the surface for a clean look while keeping clearance tight spots trouble-free. The durable polycarbonate housing handles bumps and weather without cracking or fading, so it stays looking sharp while keeping your trailer visible and compliant with FMVSS standards for trailers over 80" wide.

@Jerome Love to hear this and thanks for the feed back!

One light? For fifty bucks? I know it didn't say a pair, but I can't see where it says for ONE LIGHT. Who sells taillights indivisible? I will look for etrailer alternatives for a while.
by:
I love them they are plenty bright and affordable

The light is exactly what I needed for a replacement light on my trailer. As usual an easy purchase through E-Trailer. Fast delivery and good price!

These work well and the lights are very visible. I have these on all of my utility trailers and I think that they are a good safety backup for the tail lights. Have had No problems with water intrusion or LED failures.

Another quality product from Etrailer.com with fast shipping. Installation was simple and looks like the OEM that was replaced.

I would like to help to see if we have a light that would work for you. How far apart are the mounting holes on your trailer? The distance between the mounting holes on this light was 14.50 inches. We do have other similar lights that may be better suited. We have part # STL89RCB which is 17 inches overall and the distance between the mounting holes is 16.125 inches. We also have part # STL69RCB which is 15 inches overall and the distance between the mounting holes is 14.125 inches.

by:
Great experience, purchased replacement lights for my trailer and had it within a week. Highly recommend using their web site, user friendly.
by:
ORDERING WAS EASY. THE FIRST LIGHT I ORDERED SEEMED TO TAKE FOREVER, BUT I WAS JUST WANTING IT AND WAS NOT PATIENT. THE 2ND LIGHT DIDN'T SEEM TO TAKE FOREVER. PROBABLY BECAUSE I DID NOT NEED IT ASAP. I ORDERED 2 BECAUSE I WANTED BOTH TO HAVE ALL THE IDODES WORKING.
by:
They are easy to install and work just as described

Do you have a question about this Trailer Light?
  • Recommended Optronics Thinline Trailer Light Bar w/ Smoke Lens
    Hey Glen. We've got a couple of options for Optronics Smoke Series lights but we don't have the STL87DSRSHB which is a part number for a 10 pack. It looks like Optronics is phasing out the STL87 smoke series as well so I can't get them. I've listed our options available below: Optronics Smoke Lens ID Light Bar - Turn, Brake, Tail, and Backup Light - Red/White - 20-1/2" item # OPT55KB Optronics Thinline Trailer Light Bar w/ Smoke Lens - Brake, Tail, Turn - Submersible - Red item # OPT65KB Optronics...

  • Can The Optronics ThinLine LED Trailer Tail Light # STL87RCB Be Used As A Normal Tail Light
    Hey Jim, The Optronics ThinLine LED Trailer Tail Light # STL87RCB does have Stop, Turn, and Running Light functions so you would be able to use it as a tail light. Typically you'll see these used as tail lights on enclosed trailers because the ramp door takes up so much space on the back wall. The red wire is your stop/turn signal function, the black is your running light function, and the white wire just needs to be grounded.

  • Availability of Chrome Bezel for Optronics ThinLine LED Trailer Tail Light STL87RCB
    Hey Jim! I'm sorry to say the Optronics ThinLine LED Trailer Tail Light # STL87RCB does not have a chrome bezel that will fit. If you would prefer a chrome bezel you could fill the existing mounting holes and drill new ones to use the Optronics Streamline LED Combination Trailer Tail Light # STL89RCB. This is slightly larger measuring 17" long x 1-3/8" wide x 1" thick with 16-1/8" between the mounting holes on center. The light is also compatible with the Chrome Base # A79CB which measures...

  • Possible Replacement Trailer Taillight Strip for 2008 Sylvansport Go
    Thanks for the picture of what's on your trailer. It certainly looks like the part # STL87RCB that you referenced but might be from a different manufacturer. That said if the distance between the mounting holes on what you have is 14-1/2 inches this would bolt right up and work well.

  • How To Wire the Optronics ThinLine LED Trailer Tail Light As A Marker Light
    The Optronics ThinLine LED Trailer Tail Light part # STL87RCB is a tail light but if you were instead installing the light to act as a marker light which would be its intended purpose if installed in the center of the trailer then you'd simply need to attach the running light circuit on the trailer to the black wire and then ground the white one. The red white which is for the stop/turn circuit would be capped off. It would not be able to be used as a stop light without also working as...

  • Recommended 16" Long LED Vertical Tail Light
    We have a couple of options for vertical trailer tail lights that are 16". I have listed them below. These are our only options for 16" long LED tail lights. 16" x 1-5/16" x 11/16" - Optronics ThinLine LED Trailer Tail LIght - Stop, Turn, Tail - Submersible item # STL87RCB 16" x 1-5/16" x 11/16" - Optronics ThinLine LED Trailer Tail LIght - Stop, Turn, Tail - Submersible item # STL87RCPG

  • Comparing Optronics ThinLine LED Trailer Tail Lights STL87RCPG and STL87RCB
    The only difference between the Optronics ThinLine LED Trailer Tail Light part # STL87RCB and part # STL87RCPG is that the latter has bullet style (removable) connectors and the former has bare wire ends.

  • Is Optronics ThinLine LED Trailer Tail Light # STL87RCB Sold Individually or in Pairs
    Hey Ron, the Optronics ThinLine LED Trailer Tail Light # STL87RCB that you referenced is solid individually. If you needed two of these you'd have to order a quantity of two. Are you going to use them as taillights for a trailer?
