I would have thought either:
A) The LEDs are using the outer two contacts which are biased one direction
and have to be turned off at the battery box switch.
B) same as above but can also be turned off with the pole reverser (by
breaking that connection)
or
C) the LEDs have a built in bridge rectifier and connect to the two inside
contacts, of which can change direction based on battery box switch position
or reversing switch position.
I would have assumed A, but I do not have any of these to test.
