Based on a lot of research (mostly here and the reviews on http://www.mtbr.com/reviews/ I purchased a Dinotte Ultra 5 headlight and a Planet Bike Superflash tailight. I got the Dinotte on sale, and tried it out on the ride to work this morning. It is freakin bright. This light rocks!!! I can see the road more then 5 feet in front of me now.

Rob at Dinotte was nice enough to swap out the AA batteries and charger for some C cell battery holders and cases, he even tossed in a few extra AA battery holders and a bunch of extra straps. I got my Superflash on sale from Nashbar, and it [finally] arrived Saturday. I like the Superflash, it's really bright, but every time I order from Nashbar it takes 1 1/2 weeks for my order to arrive.
