NiteRider's Lumina Micro 220 & Solas Taillight Combo delivers the total commuting package. The headlight puts out a whopping 220 lumens, lasts up to 14 hours, and weighs in at only 126 grams! The 2-watt taillight ensures you'll always be seen by motorists from behind. Attachment is easy, too, on handlebars up to 31.8mm in diameter for the headlight, or with the included seat stay and seatpost mounts for the taillight. Plus, you can charge them both off a computer's USB port!
