A bicycle light that is constructed and arranged to be supplied with input electrical power. The power can be supplied by multiple power sources, or not. When there are multiple power sources, the bicycle light includes a circuit that is adapted to deliver power to the light source from any of the power sources. The bicycle light can have an electrical power output, and a circuit that is adapted to deliver power to the light source and the power output.

Presented here is a system and method for creating easy-to-understand notifications of the vehicle state. The notification can be visual or can be auditory and can indicate to the user the vehicle state even when the user's attention is directed elsewhere. The indication can serve to attract the user's attention before more involved information is presented to the user, such as text, or the indication can serve to communicate to the user the vehicle state in an easy-to-understand way such as using color-coded displays or audio indications. The intensity of the indication can be adjusted based on the likelihood that indication will be perceived by the user by, for example, measuring ambient light and/or ambient noise. Reducing the intensity of the indication conserves energy of an energy source associated with the vehicle.

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.
