For $28, you can get a bulletproof metal 2 x AA flashlight from BatteryJunction.com that will put out 200 lumens. You don't even need to worry about runtime, as you can get more batts or even more lights for 2-3 hr rides. It takes seconds to swap the batteries.

- Lockblocks are perhaps the best and also cheapest flashlight mounts out there. You can leave them on your bike and never have to worry about it getting ripped off.

- I've found that the best flashlight helmet mount has been a homemade one that you can make from a spare inner tube in less than a minute. Just cut a few inches worth of tube off, make holes through the walls at the ends so you can fit the end of the flashlight through them. It's analogous to using a rubber band to hook the flashlight to your helmet by looping it through the helmet. Rock-solid stable, and works incredibly well, as inner tube rubber is extremely durable. On some longer night rides, I've even mounted 2 separate 200lumen flashlights to my helmet, and ran off one of them at a time so I could just switch to the other if the batts ran down after an hour. Also was handy for going "hi-beam" when no car traffic was around.
