The present disclosure describes various aspects of crank-based lighting, which may improve visibility of pedal-based vehicles or conveyances. In some aspects, a light generating apparatus includes a crank interface and lighting system. The crank interface may facilitate mounting of the apparatus to a crank (or crankarm) of a bicycle or other pedal-based vehicle. The lighting system may generate or emit light based on information indicating an angle, movement, and/or position of the crank, such as to cause light emission to emulate or project leg movement of a rider.
