Wire 3 12-volt automotive bulbs in series. Sure sounds like your bulb is not really a 36V bulb (so bright) or else it's not made to take bumps. Something like 3 marker light bulbs would provide about the same wattage, and you know that they are able to take the bumps.
Some electric forklifts run on 36 volts. A forklift dealer might be able to supply a better headlight for your scooter.
put a diode or two in series with the bulb to lower the voltage. your problem will go away. Refer to standard equations for bulb life to understand why
To get a 10:1 increase in life (to 10 hours), the usually quoted 12th power relationship would require a 21% drop in voltage, or about 7 volts.

So with a few extra wires and a switch you could alternate the 'headlight' battery and re-balance the batteries.
OK, then make it four silicon diodes in series.

Ummm, Jim, I'm sure you realize that 4 x 0.7V is somewhat less than 7V.

Interesting part. I figured the TO-220 "simple switcher" might be easier for Charles to use in a one-off -- no circuit board.
I agree. ;-)

Tungsten filament light bulbs try to act like constant current devices. Unless you have a perfect match up, I would be _very_ surprised if the
6V bulb dropped 6V.Ted
Do you have a part number and source for that?

See previous post. Also, go to
There is also a website that selects a part for you given your requirements at
These things are dirt simple to use!
Oops, missed it. It will for a little bit, but not for long. It's a nice and easy first thing to check. Probably not very likely.
