I think I've invented a way to run lights from our china girl magneto white wire with no loss of performance, or dependability, and still have a very bright light. Actually I designed this devise for my moped so I could use a Cree LED light bulb, but it should work fine on a china girl with any kind of LED rated for 6 vdc. The magneto white wire on our beloved china girls puts out something like 6 vac. That's what I've been told. I haven't actually got around to checking it yet, because I read on the forum years ago that it's useless to use the white wire for lighting because it robs to much performance to be worth it. Mopeds also run their lights on ac volts, so I had to invent some kind of rectifier to use a Cree bulb. After a little trial and error I now have a good working and dependable rectifier. About the only difference between my moped's magneto, and a china girl magneto is, my moped puts out regulated 12vac, but our china girl's put out unregulated 6 vac. I don't think that will have a great effect on what we're trying to do, which is have lighting without using batteries all the time. The voltage being unregulated won't make much difference, because most LEDs tolerate a somewhat wide range of voltage, and since our magnetos are so weak I don't think we need to worry too much about blowing up our bulbs from too much voltage. This rectifier can be duplicated for about $5.
