I don't know what outputs the proposed E-unit provides; but you can wire directional LED headlights in a simple way from the motor voltage: Connect the two LEDs in anti-parallel, that is, connect each cathode to the other LED's anode. Connect the ballast resistor in series with the anti-parallel LED circuit. Connect the entire series circuit to the motor voltage. No other diodes or resistors are needed. Only one LED will light, depending on the motor-voltage polarity.

Have used U-33 that has a bad old style factory E-unit that has gone bad. Wish to install new model Universal E-unit. Does anybody have an appropriate wiring diagram?
