    can you change a generator light to battery?

    My wife wants a specific look for this project, and part of that is a 40's-50's style headlight. I've found them with generators, but she informed me that she does not want a generator, she wants batteries. since it's electricity, I will make the huge leap of logic that all I will need is a battery, terminals, some kind of housing, a switch and the light(s). I'm not looking for KC daylighter output here, just enough to approximate what a generator would produce, or hopefully a little better.

    I Would love some input, thanks.
    I am looking for a 52cm-ish lugged mixte or ladies frame. Pm if you got one.

    First you'll need to know what voltage the bulb requires. I expect most are 6V but they may be 3V or 12V. The bulb really doesn't care where the power comes from.

    Second, most bulbs used with generators that I know about are 3 watts so the battery size will depend on how long the light is expected to run on one charge. For example, to get a two hour run time at 6V you will need a 2 amp-hour battery. Larger batteries will give longer run times.

    SLA (sealed lead acid) batteries are the lowest cost but heavy for their capacity. NiCd, LiMH and Li-Ion are respectively lighter and more costly.

    Before you decide against a generator light, have you seen the Busch-Mueller Lumotec Retro?

    I am not against a generator light, I have one on one of my bikes. She does not want the extra drag, although that light is almost the exact style I'm looking for.

    Sadly, I am not in the market for a dynamo hub, which would be my preferred option. I can't afford one at the moment, and I am not going to relace a wheel for this particular bike.

    Bike World USA has the light you need. It uses two "C" batteries contained within the light for a clean and easy install and use.

    Did this years ago when I converted a Union 6 volt generator system. I bought from Radio Shack a battery pack for 4-D cells and a simple rocker switch. Not exactly dainty or compact, but has worked reliably on 2 bikes and still use one of them today while the other sits in the closet.
