>>1310115Cateye makes a decent 300 lumen headlight for $30 USD. It's waterproof, has a good mount, recharges with USB, has a replaceable lithium cell, and it's an all metal construction. The beam pattern is a tighter than I'm used to, but it gets sufficiently bright for my needs. I usually run it on the medium or low setting. It has a nice low/flashing mode, too.
>>1310150This is the kind of system I believe all night-time commuters should work up to. The dynamo lights with their asymmetrical beam patterns are greatly appreciated by on-coming traffic for their visibility and not blinding them in the slightest. Not having to worry about batteries is really nice. Whenever the bike moves, there is good light. (Pic related.)
