If you don't have a ton of money to spend I recommend the Planet Bike Blaze 2 watt headlight - $54 - $59. *(I've owned the Blackburn 3.3 too, it's bright. If you have no occasional street lights on your ride, you may want a rechargable system.) I used to ride with two Blackburn 3.3's strapped to my old bikes handlebars. It worked well. I was able to point one on flash a head of me towards any traffic and one down at the road to illuminate potholes and other obstacles. Boy did cars slow waaaay down when the one was on flash. They often stopped and said they thought I was a moped. That's some visibility.
