Optronics STL76 Series ThinLine Tail Light for Trailers over 80 In Wide Diagram

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.

I bought this to replace the third high mount brake light on my 4 Runner. I wanted a brighter light due to the large number of drivers on cell phones and not paying attention to traffic. This light is at least 8 to 10 times brighter and is absolutely perfect.

I mounted it directly on top of the existing light and just drilled a hole through that light to run the wires. I used two sheet metal screws to secure it to the frame and filled the open space in with clear caulk. I did not use the existing mounting hole because I wanted to aim the light into the face of the driver behind me. Seriously, we have a real problem with drivers on cell phones.

Shipping was fast. I was stunned that the light was packed for shipment in 3 hours on a Sunday morning. You people should really take Sunday off.

One year later and this light still looks brand new. It survived an unusually harsh winter with no problems. It is definitely a FIVE STAR LIGHT.


I ordered this part on a Thursday PM, Friday came and I heard nothing of shipping.. I did receive and conformation notice. Nothing Monday. Tuesday I went to etrailer site and inquired about my part... Later that afternoon my part was shipped. I had the feeling that nothing would of happened sooner if I had not inquired at etrailer's site. The part is great. I love it...


This was a replacement for one that got damaged these are very bright tail lights and look better then any thing I have seen on trailers in my area. Sorry I do not have any pictures at this time.


Just like the ones I took off only new. The old ones were 10 year and were starting to fail. This was a good fix


A little brighter than the LED lights I had but much larger so I'm pleased with the improvement. Great light for the money!



Consistent performance, no complaints


I bought these lights to install as a third brake light replacement and I wired them to the tail lights so they work also. I have a 38 foot Itasca Suncruiser motorhome now the rear is very brightly lite up what a difference from the cheap original led lights. They are very bright and good quality lights well worth the price. Thank you



Still working and look nice after one year. A nice improvement over the old lights and have held good as they are outside in the elements


Purchased some new LED lights for trailer. eTrailer has good prices and a good selection. Shipping was a bit slow but that may be be eTrailer's fault, we all know how the postal service works...or doesn't.

No reservations about re-ordering from this company, I like that George followed up with me afterward to make sure I'm satisfied.

I only wish the descriptions on the lights told you if the light was all plastic or metal. Having side that though, I'm not sure it's even possible to get an all metal light anymore.

Order with confidence!


Very fast shipping easy install works and looks great


Great Easy To Install Very Bright. Happy With This Light System On This Trailer And The Safety From The Brightness Of the Lights Means A Lot On The Roads We Travel In Heavy Traffic.


For the application that I have planned, these will fit perfectly.
Mounted to a cargo carrier attached to my Honda Trike, for extra lighting and for times when the cargo covers my existing lights.


It makes absolutely no sense that the E trailer website sells these as singles not as a pair. Any other retailer that I have visited in the past two weeks sales trailer lights in pairs. If E trailer chooses to sell these as a single, then the web page where one purchases these should clearly indicate that you are only buying one of a pair. That page should also boldly offer the option of buying a pair so that there can be no error in ordering.

This is not rocket science. It is simple retailing.


I was looking for some large lights to put on the rear of my trailer high on the rear for the traffic to see.
These lights are large enough and with the LED lighting they will be visible for 4 or 5 cars back in the traffic.


great bright led. sealed. The best way that you can tell about a seller is the way that they handle a problem! One of the lights had a crack that could only be seen when subjected to a light source. I noticed a crack when it was sitting in the sunlight waiting to be installed. I sent an email and it was immediately replaced. I will check with this seller prior to my next purchase and buy from them if they have what i am looking for. ***** for 5ive stars





working just fine,amazed at the price..


Ordered LED Lights for a trailer project. They were good value, fast shipping and communication was great.


Trailer lights were an exact fit and delivered really quick. I installed them today and they worked perfect. Thanks.


Use these on my charter boat trailer. They work great, the left one is right under the fuel fill of my boat and over time the gas has faded the lens. Started looking for for the same lights to replace it, and not only found the light, had no idea I could just replace the lens. Very convient and user friendly product.


No local retailer handles the lights I need for my stock trailer, so I found them on etrailer and glad I did. Any trailer needs I'll go there first.


I'm using this on a 1955 Ford F-600 Rat Rod Dump Truck. They fit perfect on the dump body sides. They are extremely bright even in broad daylight. I liked that the wiring diagram was molded into the housing. Quick cheap delivery via USPS too!


Great product, bright, thin and low profile! I mounted them on rear riser of my enclosed trailer.


The light has been installed on a Dodge Van RV. The extra length was needed to cover the hole in the fiberglas top cover. It looks and works great.


Works great. Not the ideal size, but the closest we could find for our original light.
Easy installation.


Great light. Used as replacement high brake light on my RV when the original sockets rusted. Very bright. Wired for brake only.


Product was perfect. Best price and actual shipping costs!! None of this shipping and handling $10.00 crap. Thank You!! This is why I always come back to etrailer.


Product arrived as described and easy to install.

  • Are Load Resistors Needed When Converting Trailer Taillights to LED
    You never have to install load resistors on a trailer when converting the taillights to LED. The only time you have to do that is when converting a vehicle light from incandescent to LED.

  • Availability of a Long Thin LED Stoplight for Trailer

  • 13-1/4 inch Long Led Light Bar Recommendation
    It sounds like you are looking for a very specific light bar. From looking at what we have it doesn't appear we have exactly what you are looking for, but the closest thing we have would be the Optronics Trailer Lights # STL76RB. I attached a review video for you to check out for this light. You may find that it could work for you.

  • Can Optronics LED Trailer Light # STL76RB Be Used as 3rd Brake Light on 1996 Georgie Boy RV
    Yes, you can use the Optronics LED Trailer Light, part # STL76RB, as a third brake light. To install, you would just connect the Red wire to the brake light wire on your 1996 Georgie Boy RV. Then connect the White wire to a clean metal surface for the ground. The Black wire will be taped off and tucked out of the way, since it carries the tail light function and will not be used.

  • Replacement LED Trailer Tail Light Strip With 11 Diodes and 13-1/4" Long
    The ThinLine LED Tail Light # STL76RB is our closest light to your current tail light. This light is 13-1/4" long, 2-1/8" wide and 1-7/16" tall. It also has 11 LEDs like your current light. For your tail lights you will need to verify if they used the mounting hole as a ground connection and the 2 wires you have one will be for the running lights and the other operate the turn/brake wire. A Test Light # PTW2993 can be used to test the function of each wire. If that is what you have then...

  • How to Wire LED Trailer Tail Light STL76RB to a Trailer Side 4-Way Connector
    First, you would want to use 2 of these because otherwise the light would blink with either turn signal. What you you would do is take a trailer side 4-Way, # A35W42B, and attach the lights wires to it as follows: On the driver side you will attach the white wire to the truck frame or to the white wire on the 4-Way. The red wire would go to the solid yellow wire on the 4-Way. The black light wire attaches to the yellow with brown stripe wire from the 4-Way. On the passengers side do the...

  • Upgrading Camper Lights to LED and Clearance Lights with Brake and Turn Signal Functions
    You can upgrade to LED lights but what I need to know is if the camper has the brake lights and turn signals on the same bulb or if it has separate amber turn signals. And if the camper does have combined brake and turn signals do you want to keep it that way or do you want to have separate turn signal and brake light circuits? We have several options for double tail lights, such as # CE86FR, and even some triple applications such as # 47-84-005. Depending on if you want combined or...

  • Availability of an LED Trailer Tail Light Kit that Will Fit a Snowmobile Trailer
    In terms of a pre-assembled kit with everything included, the closest we have to something with tail lights that are 2-1/2 inches tall would be the Trailer Light Kit with 25 Foot Wiring Harness, # TLL16RK. The included tail lights in this kit are 2-7/8 inches tall. Another option would be to get a couple of # STL76RB lights, and a 4-Way, trailer side wishbone wiring harness, # A35W42B. I have included a link to a video showing the installation of this wiring harness for reference.
