Question:
Hello, do you have an equivalent product that would be a direct replacement for the following: Round LED Truck and Truck and Trailer Lights with Reflector Flange from superbrightleds. This company that I bought from before no longer sells the red version which I need to replace. Thank you!

Hello Britton; the closest thing we have is the Optronics LED Trailer Tail Light # STL42RB. This has the same 5-1/2" overall diameter and requires a 4-1/2" round hole for installation. It also uses the same 3-prong plug you have now. It has less diodes but it is still a bright light. The number of diodes doesn't necessarily mean a light is dimmer or brighter.
The one thing I didn't see listed is the distance between the mounting holes. The Optronics light measure 4-1/4" center hole to center hole so you can compare that to what you have now. If nothing else you could drill new holes for installation. If you want one with the reflector we also have the # STL43RBX which has a slightly larger outer diameter at 5-3/4".

Hey Britton, how did the fit work out with the Optronics LED trailer tail light you tried as a replacement? It’d be great to know if the mounting holes lined up or if you had to make new ones. Your update could make it easier for others replacing similar lights.
