But there are 4 of them in an H configuration. These 4 diodes end up working like a rectifier bridge; no mater which way the motors generate electricity, the diodes funnel + voltage to the +batt and the - voltage to the -batt (a.k.a. ground).

This is why the lights come on no matter which way you turn the wheels.
