    Light switch

    Is there anyone who have seen an automatic lightswitch (except Shimano) for dynamohub. There are more and more dynamohubs but hard to find switches for them

    Couldn't you just leave it in the "on" position all of the time? The bulb would only illuminate when the wheel is turning, and there's no battery to drain.

    Won't any switch from an electric parts or home improvement store work? A switch is just a switch.

    There are a few ways to solve your problem.

    – A separate electric switch should do it. The challenge is to find a waterproof switch and to attach it to the bike.

    – Get a switched Lumotec or Schmidt headlight. Not only many models have a switch, but they do have voltage control to prevent overvolting the light.

    – Get a LED-based headlight such as the Inoled or DLumotec. Since there is no bulb to burn, you could use it all the time. Resistance with a working headlight is negligible with a Schmidt dynohub, but is more important with other hubs.

    I think that the OP is interested in a photoelectic switch, so that the light will only be illuminated when it's dark outside. I'm not sure if the OP is concerned mainly with pedaling resistance or bulb life, but Michel Gagnon's post offers suggestions for addressing both issues.

    I thought that American Science & Surplus or Radio Shack would be sure-fire sources, but I couldn't find anything suitable on their websites.
