Optronics STL79 Series Streamline Sealed LED Combination Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

Surface-Mount Light

Surface mount light

Surface-mount lights install flat against the surface of the trailer, so a hole does not need to be cut into the trailer for the light. This type of light is installed using a flange or bracket that has mounting holes. And mounting hardware is used to secure the light to the trailer.


  • Overall dimensions: 17" long x 1-3/8" wide x 1" thick
  • Distance between mounting holes (center on center): 16-1/8"
  • Diodes: 11
  • Power draw at 12.8V:
    • Stop/turn: 0.35 amps
    • Tail: 0.022 amps
  • Lifetime warranty on LEDs

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.

The lights are perfect, same as what I had and I would order more products if I need them .

Mounts easily on snowmobile trailer. Lov it. Fits inside frame chan. Buy it!!!!!!!


Bright LED light. I always buy all my horse trailer replacements from E trailer . Great customer service!


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.


Best no nonsense review I can give, The product was as described, etrailer shipped the part properly and on time.


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


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..


Great quality, look great on my flat be d!


They look awesome


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.

Still working great

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.

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.



They work great , We put these lights on everything we build


Great product, perfect replacement easy to install!


Although it is not a perfect match of the oem it will work fine,


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


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.


Purchased replacement LED tail lights. Lights arrived in a timely manner and are an exact replacement by part number.
Thank You for the timely service.

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

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.

the lights work perfectly

Great service ,quick delivery.Very sati sfied


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


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).


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.


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!


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!


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

I will be back in the future.
