Further: the remote tail switch should be an active device, dropping no power. This has been demonstrated on here by simple FET circuits in the tail, Lexel makes them.
A hunting torch needs no driver in the head, or UI, just on and off. If multiple LEDs are to be used then that gets more complicated, maybe a simple driver in the head using three FETs., with the remote tail switch plugged into the side of it and a basic communication protocol. E.g. main switch on or off, second switch cycles between LEDs.
