Your friends bike is probably right on the edge like most of the guys that use the magneto to power lights. IMO it is a bad idea to power anything with the white wire for two reasons:
1. It robs power from a marginal ignition.
2. Life of a less than reliable coil is compromised.
I use an LED bike headlight off 3 AA Hybrid rechargeables that has 6-7hr run time. It's twice as bright as my buddys ignition powered system. He needs to keep his plug gap way down and constantly has trouble starting too. Also brighter and more reliable than another local fellow with 6v gel cell setup.
