I do a lot of night mountain bike riding, so have good lights from that, but I actually love them for commuting as well...I used to just use a few blinky lights, $20.00 bucks or so from the local bike shop...but I recently bought a few Exposure lights for night riding, and my night commuting has gotten way more fun...my bar light is the 1200 lumen Toro and helmet light is 1100 lumen Diablo...I also use a rear blinky just for extra lighting. It might seem excessive, but I think there is nothing better than being 100% confident that I am seen and I have a lot more fun, and feel that I have more freedom to ride around at night...they are pricey, but definitely worth it to me
