Hi Keith!
I have a way to make the Optronics Trailer Tail Light - Stop, Turn, Tail, License - Round - Red Lens - Driver Side # ST21RS into an LED light, but Optronics does not offer this one as an LED.
If you replace the incandescent double contact 1157 bulb with something like the ARC 1157 LED Bulbs - 360 Degree - Double Contact Bayonet - 600 Lumens - White - Qty 2 # ARC93FR, it would be a much brighter light. This also includes two bulbs, so you could also do the passenger side ( # ST20RS).
Out of curiosity, what do you want to install this on?

Hi Keith, Did you have a chance to try the LED bulb replacement for your trailer tail light? I'm curious to know how it worked out for you, as it could help others looking to upgrade their lights.
