I use a Nightsun Team Issue housing with two 50 watt halogen bulbs clamped to my handlebars, polarized trailor hitch connectors on wires leading to an adequate battery in a pannier and an intelligent charger. Or just buy a much neater setup from NightSun for ~$175 or so.

For some real fun You could build a 100 watt headlight for just under that $150.00 based on a Cessna landing light.
