Can you connect them to any of the old generators, either bottle generators or dynohubs?
A few years ago a bike shop tried to tell me that the old dynohubs didn't put out enough power (I questione d this, but had plenty of other lights including 10-15w halogen lights, so I didn't spend more time or money on this.)
I think the old dynohubs have more magnetic poles than the bottle generators - does this make a difference?
I have bottle generators (original lights, I think both original) on a 1960 Gazelle and 1964 Rudge, it would be nice to make them more useful at night.
Thanks for your experience, or any other help.
