LOL! True... that describes most attempts to power a light from the white wire. What many "weekend engineers" overlook is that these bike magnetos are marginal at best and it's a miracle they power the ignition. I made many attempts myself but nothing that lasted long enough or worked well enough to be of any practical use.
Best solution was to use a 106 LED headligtht using rechargeable AAs. Floods the road with light for 5-6 hours on a charge. Using new "hybrid/precharge" type NiMh the light is always ready to go.
