Biking anywhere other than your driveway is inherently dangerous, especially at night. Because visibility is paramount, a bicycle light is a worthy investment in your safety. Typical bike lights illuminate your path and alert incoming drivers to your whereabouts, but do little to protect you from a turning driver’s blind spot. The Blaze Laserlight ($200+) solves this problem by projecting the image of a bike up to 15 feet onto the road ahead of you via a green laser. This lets other drivers know of your presence, preventing them from turning into your oncoming path. Its waterproof, aircraft aluminum construction houses a Li-ion battery thats good for around 13 hours of ride time.
