Hey, Travis.
We do have a light that can work as a replacement, though it won’t be an exact match. The closest option is the Diamond LED Trailer Tail Light with Reflector, part # DG52721PB.
This light measures 11" long x 8" tall x 1-1/4" deep, so it’s a bit larger than your current Bargman lights. It also includes a 5-wire pigtail, just like the older Bargman models, so wiring will be familiar and straightforward.
