Features to know about

Brighter, Longer-Lasting, and Efficient: 11-Diode LED Performance

This ThinLine LED tail light puts out a clean, bright red signal that’s easy to see day or night. Inside are 11 efficient LEDs that handle stop, turn, and tail functions without the fragility of old-style bulbs. The LEDs last up to 50 times longer than incandescent lights and draw less power—only 0.275 amps for stop/turn and 0.022 amps for tail at 12.8V. That means less strain on your electrical system and no bulbs to replace down the road.

Worrying About Water Damage: Sonically Sealed and Fully Submersible

If your trailer ever gets wet or even submerged, this light is built to take it. The housing and lens are sonically sealed into a single waterproof unit, keeping out moisture that can corrode circuits or kill your LEDs. Whether you’re driving through heavy rain or backing into the water, it stays sealed tight and shining bright.

Tight Mounting Spaces: Low-Profile ThinLine Design

When space is limited, the ThinLine shape fits where standard tail lights won’t. Measuring 13-1/4" long x 2-1/8" tall x 1-7/16" deep, it mounts flush to the surface without cutting any large holes in the trailer body. The low-profile oval design keeps things sleek and out of harm’s way while still meeting SAE T2 I6 requirements for trailers over 80" wide.

Surface-mounted Optronics ThinLine LED Tail Light shown installed flat on trailer surface, illustrating flush mounting style.

Simple Wiring Setup: Straightforward 3-Wire Design

Hookup is quick and clear with a basic 3-wire setup—one each for stop/turn, tail, and ground. The surface-mount design uses 12-7/8" center-to-center mounting holes for easy alignment, and hardware isn’t included so you can choose the right screws for your surface. Once connected, you’ve got a dependable LED tail light that’s ready for long-term duty with a lifetime warranty on the LEDs.

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



by:

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.



by:

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.



by:

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



by:

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.



by:

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.



by:

too wide. My fault!



by:

I haven't installed it yet but is the right one. I spent a month looking for a replacement and was assisted in finding the right one by being referred to you by the StreamTech Boats folks, from whom I originally purchased the raft and trailer. Thanks for the rapid response.



by:

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.



by:

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



by:

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!



by:

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...



by:

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.



by:

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.



by:

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



by:

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!



by:

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



by:

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



by:

Very fast shipping easy install works and looks great



by:

This was the perfect fit for my applica tion



by:

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.



by:

Exactly what I needed



by:

Perfect fit for replacement lights on my enclosed trailer.



by:

Quality product. Shipping laser fast. Great price. What else to say. Would I buy again "YES" absolutely!



by:

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.

  • 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...

  • Recommended Lights and Parts Needed To Install Tail Lights On a 2024 Cushman Hauler Golf Cart
    Rather than use the single Hot-Line 3rd Brake Light # 328-003-6017X I recommend using 2 of the ThineLine Tail Lights # STL76RB. With this you can mount both to the roof with one on each side. This will allow them to act as turn signals and brake lights as the one you found does not have separate wiring for each turn signal. As for the wiring you will need to find the brake light circuit on your 2024 Cushman Hauler 1200 golf cart so you can splice the Converter # HM48847 into it and the...

  • Recommended Mounting Screw For A Thinline LED Tail Light # STL76RB
    Hey Steve, The ThinLine LED Tail Light for Trailers over 80" Wide # STL76RB has 1/8" diameter mounting holes so a #4 self tapping screw would thin enough to fit through them and mount the light to your trailer. Are you mounting into metal or a different kind of material?

  • 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...

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...

  • 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.

This light has an overall measurement of 13.26 inches long, 2.13 inches tall, and 1.42 inches deep. You will need to splice into the wires on the lights once they are installed.

  • 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.
