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.

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. 696290


Got just what I needed. And it was a no hassle purchase. 619906


Trailer lights were s perfect fit. 597869


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. 590078


AAA +++ perfect item as described 576250


Good quality and works as it should. 554200


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. 517177


Trailer lights were an exact fit and delivered really quick. I installed them today and they worked perfect. Thanks. 496857


Very satisfied with lights. They are a perfect match for the old ones. Fast deleivery and good price. 493988




Very fast shipping easy install works and looks great 391486


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. 376815


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! 373599


Got my lights quickly and as described 348858

They are working great!
Keri H - 03/05/2018



Services rendered were fast and flawless. Products were exactly as advertised and product information very helpful. 347956


Light came in a timely manner! Easy to install works fine. 347719


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 344704


My order was shipped promptly and was just what I ordered. 319781


Light was exactly the same as was original on the trailer. Works good. 316662


Ordered LED Lights for a trailer project. They were good value, fast shipping and communication was great. Thanks 309391


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! 192488


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. 172955


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. 156622


Product was a expected and communication and service was very, very good. 122343


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. 104701

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.

  • Long Thin Trailer Tail Light With Chrome Base
    We have a long, thin trailer tail light with a chrome base, but the Optronics Thin Oval LED Tail Light, # STL76RB, does not have a chrome base option. Another light that you may be interested in is the Optronics Sealed Thin Line LED Trailer Light, # STL69RB, and the Chrome Base, # A69CB.

  • 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.

  • 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...

  • 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.

  • Upgrading Camper Lights to LED and Clearance Lights with Brake and Turn Signal Functions
    Yes, you can upgrade to LED lights and have a double light set up in the rear with stop, tail, and turn light functions. 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 # 47-84-610,...

  • 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.

  • Recommended LED Tail Lights For Hitch Mounted Carrier On 2007 Honda Element

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. I recommend using a trailer-end 4-way connector for the lights like part # W787264. This has the 4-way connector that will attach to the trailer connector on your Element...
