That light ypedal posted is really neat, but around 200 to 300 $USD. Ouch. Probably fair for a high end product on an investment electric bike, though.
Those bi-pin 12v bulbs with the built in glass are really nice. I have couple 20w spot beams that I use in the winter, with home made PVC housings, and bi-pin connectors I got from a custom-lamp and electrical supply store. (about $1-10 each for the connectors, the kind with the built-in clip is far best. The bulb pins are delicate and DO NOT like being soldered (they break off). 1 20w (non LED) bulb runs about 1-2 hr with a 7AH sealed lead acid battery (heavy too for mtn biking!).
I agree, the best thing in the world with a DC setup is a LED light system, home made or commercial. It makes a pleasing white light.
There is a danger though! Some objects do not register well at speed with certain frequencies of light! It takes some getting used to when you are used to halogen or inandescent light!
There are lots of commercially available mtn bike lights for bar or helmet mount, with remote batteries such as Nickel Metal Hydride and now lithium batteries, with car chargers and smart chargers often included. Usually around $70 for a light, to 100-400 for a light and battery and charger. Some small niche manufacturers make some really good and very small ones out of CNC aluminum and hi-tech electronic and light parts. Try searching the web and bike catalogs for "adventure racing" lights or mtn bike lights. This stuff has come SOOOOOOOOOOOO far since the days of cutting your own box from sheet metal, installing hardware store and auto bulbs, and wiring to motorcycle batteries.
