Have you considered a dual lighting setup? That's what my wife's got on hers. Primary lighting coming from an internal front hub generator. Every so often though, from hitting potholes, bumps, or whatever, some connection gets loose and she loses her light. If that happens, she's got a secondary, handlebar mounted 2-C cell halogen. If your battery light is only secondary, you shouldn't have to replace batteries very often, but if your generator light happens to whack out, you're not stuck in the dark???
