Expert Reply:

The Optronics Fleet LED Trailer Tail Lights # TLL12RK are a slightly longer light so they aren't a replacement, but we do have the LED replacement you need for the Optronics # ST70RB.

That part is the Optronics LED Trailer Tail Light # STL72RB.

This light uses the same PVC Grommet # a70gb with the 3-wire Pigtail # A45PB or # A47PB (right angle pigtail) for installation. I have added a link to a video review for you to check out as well.
