How to Mount Trailer Light

Surface Mount Trailer Light Installation Diagram

This light is a surface-mount, meaning it installs flat against the surface of the trailer instead of through a cutout. Use the built-in flange with mounting holes to secure the light.


You can also add the optional snap-on reflector trim ring (A78RXB - sold separately) so your tail lights are more visible.

These look great and are bright. A bit difficult fit for replacing the old lights but the electrical connection was the same. Overall we are very happy with them.

eTrailer was also awesome with the order process and very helpful

  • Does Optronics Clearance Light # STL733RB Come with Reflector Ring
    Hey Michael, so the LED Trailer Taillight part # STL73RB does not come with the reflector ring you asked about but you can pretty easily add it with the part # A211RXB.

  • Is Gasket Needed to Install Optronics Trailer Taillight # STL73RB
    Hey Eric, we do not have a gasket for the part # STL73RB as it does not normally need one.

  • What Reflector Ring Fits the LED Trailer Tail Light # STL73RB?
    I confirmed with my contact at Optronics that the reflector ring that you need for the LED Trailer Tail Light w/ Flange - Stop, Turn, Tail - Submersible # STL73RB is the Snap-on Reflector Ring for STL78RB Series LED Lights # A78RXB.

  • How to Wire Optronics LED Trailer Tail Light w/ Flange
    I do not have a schematic but I can tell you how the LED Trailer Tail Light w/ Flange # STL73RB should be wired. The white wire will be your ground source, the black wire is for the running light, and the red wire will be for your stop/turn signal.

  • Replacement LED Tail Light for Triton Boat Trailer Part # 08478
    I was able to pull up some information on the Triton 08478 light that you mentioned and it appears that the LED Trailer Tail Light w/ Flange - Stop, Turn, Tail - Submersible - 6 Diodes - Oval - Red Lens # STL73RB is the same part. I've linked a photo with the dimensions of this light, but it is also an oval LED light with 3 wires like the 08478, so it should do the job for you. If you've got a different sized light just let me know and I can see what we have available that would work.

  • How Does Taillight Ring # A78RXB Get Removed
    To remove the ring # A78RXB you basically would want to grab one side of the ring and gently pry up on the ring till it releases from the mounting flange. If it does not want to remove this way you can use a thin slot screwdriver and slide it down into the slots on the sides of the light. This will allow you to push on the hooks of the ring so that they will release from the light. See picture to see where to insert the screwdriver.

  • Will I Need any Additional Wiring Or Adapters When Changing to LED Trailer Tail Lights?
    The LED Trailer Tail Light w/ Flange # STL73RB will mount in place of your non-LED trailer tail lights. There are no other parts needed as the tail lights on your tow vehicle will control the flash rate. The lights will work with your older truck just like newer vehicles. The only exception is some Mercedes, Audi and other vehicles which have trailer lamp detectors built in which would confuse LED lights with a bulb being out. Those vehicles would need a Lamp-Out Sensor Bypass Adapter # 20142.

  • Optronics Thinline LED to Replace a TecNiq T16
    I have a solution for you but we do not carry the TecNiq T16. I recommend the Optronics Thinline LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 15 Diodes - Red Lens item # STL64RB. The sonically sealed, waterproof housing and lens unit is submersible. This light has identical dimensions at 20-1/2" long x 1" tall. It has the same three functions with brake, tail, and turn. The Optrionics is a better light with 15 LEDs over the TecNiq T16 13.

  • Is There An Amber Version Of The LED Trailer Tail Light STL73RB?
    I have a different option for you, but the LED Trailer Tail Light # STL73RB you were looking at is not available in amber. This is due to tail lights needing to be red to be in accordance with laws here in the USA. The closest amber light is going to be the GloLight LED Side Marker Light # STL175AMFB which is virtually the exact same size at 7-7/8" long x 3-5/16" tall and can be used as a side marker light and a turn signal if you desire. I included a video of the # STL175AMFB for you...

  • What Circuits Does LED Trailer Tail Light part # STL73RB Cover
    Yes, the LED Trailer Tail Light part # STL73RB does perform function of running light, brake light, and turn signal. The low illumination circuit is for the running lights and the brighter is what activates with the brake and turn signal.

  • How to Determine Correct LED Tail Lights For Rolco Trailer
    Hey Daran, The numbers you gave don't correspond to any light I could find, but it's easy to find the right one. All you have to do is measure your current tail lights and find the one that most closely matches your measurement, and also know if your lights are surface mounted or recessed mounted. For example, the Optronics LED Trailer Tail Light # STL73RB has a light face which is 7" long x 2-3/4" tall and is surface-mounted. If you let me know what your light measures and how they...
