Traditional bike lights solve several problems — they let you see where you're going, and they let other people see you. But they won't stop a driver from turning into you if you happen to be in their blind spot. The Blaze Bike Laserlight will. This ingenious add-on serves as a traditional front-facing lamp, but also includes a green laser light that projects the image of a bike on the road roughly 15 feet in front of you, letting motorists know you're coming before you're even there. The internal Li-ion battery lasts for up to 13 hours, and the body is waterproof, so the only thing you really need to worry about is pedaling.
