How many volts is the Vistalite bulb? Give it a try with the dynamo as you normally cannot damage the dynamo. I would be surprised if it gives out enough light to actually illuminate the road adequately though.

The hours I gave were listings frojm a web site with no other information given. If using an older headlight w/o overvoltage protection the life could be pretty short for a fast rider I understand. Some of the old dynamo setups were apparently pretty notorious for blowing bulbs at high speed.

To maximize bulb life w/o adding zener diode protection the Shimano halogen bulb dynamo headlight uses a 9.6 volt 5 watt bulb. Normal German halogen dynamo lights use a 6V .4 Amp or .5 Amp halogen bulb so either 2.4 or 3 watts rating at a lower voltage.
