Petzl Tikka FTW. Killer run time, light weight, cheap, helmet mounted.
Me and Shaker666 hit Fromme for a snowing night ride down Pipeline and the lights I brought shit the bed and shorted out 5 min into the ride. So I slapped on my Tikka and flowed Pipeline. Killer ride and the Tikka really impressed me.

In snow, you can get away with a much lower output light. The Tikka would be an awesome emergency backup, but with a max output of 50lumen, it's not bright enough for regular riding without the albedo of snow.
