Motorcycle headlights without a battery?

i'm seeing custom bikes w/ headlights but no battery. (racer style cafe style etc.) are they hiding it, or running straight off the alternator/generator/magneto ??

obviously this would mean kick or bump starts only and headlights only while the engine is on. but how is it done?

They use a battery eliminator. This is a capacitor installed to replace battery.

Also many magneto bikes did not utilize batteries. (ex XLCH) The mag supplies power for ignition circuit and generator (dynamo) or alternator (stator) supplies power for all the rest. Some early bikes only had a mag for all power

And the lights are not only when the engine is on but only when it is rapping fast enough to spin generator and produce electricity. (no lights at an idle)

I ran my 1978 Honda XL 350 with a totally dead battery for years. Yup, kickstart, and the headlight was on only while the engine was running.
Stator to voltage regulator to headlight. Thats how it is on my 1985 XR200R. Light when runnung even at an idle.
