Looking for 20 inch by 1 inch Trailer Taillights for Trailer

Question:
I’m looking for two waterproof LED taillights that have running, stop and turn functionality. Trailer has a four wire system and to cover the existing size I’d need 20” tall by a minimum of 1” to 1 1/2”wide. Thank you, I appreciate your assistance.

Hey Dan, the trailer taillight we have that most closely matches what you are looking for would be the Optronics Thinline light bar part # OPT65KB which is 20-1/2 inches long and is 1-1/16 inches wide. Would that work? It has the standard trailer taillight functions too of stop, tail, and turn which match what your wiring has as the additional circuit would be the ground circuit.
