Enhance your nighttime bicycling safety with the Laser Bicycle Lane. This waterproof and shockproof device features two highly visible red lasers that project a pair of red lines onto the street. This virtual bike lane creates a boundary for motorists and other cyclists to respect, and is visible up to a mile away, even under headlights and street lamps. This super-lightweight device (0.12 lbs.) also functions as a safety tail light, with five bright red LEDs that flash or stay on continuously. Includes mounting bracket.
