"USA friendly"?
Does that mean going back to the 1960s-style 4-wire scheme with one brake light if you're using the turn signals?
When changing to LEDs, it's easy to maintain the amber turn and red brake lights, and even add features like white reversing light. Personally completed the mod on three Cobra trailers in the USA.

Any USA glider trailer going to Benalla will need proper lighting. 4-wire and red turn signals are illegal.
