These magnetos produce pulsating alternating current . Like most any bike . That's why a regulator/rectifier is used . The rectifier switches the AC to DC to lengthen the life of component accessories ( lights and such ) . It should be noted that some fixtures only use DC and some are not as 'picky' and can run on either AC or DC . The regulator helps keep the voltage within a given parameter , helping smooth the current flow ( less stress ) . (edited)
