Small and lightweight. That gives continued glow when the bicycle is stopped, steadier glow when moving and is a very simple way of protecting the LED headlight from overvoltage. You need the NiCd battery, LED and it's resistor, and maybe a protect zener and on/off switch would round it out nicely. Nothing too complicated there.:o) -Roman -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
