A bicycle lighting system has a lighting mechanism attached to a wheel of the bicycle. As the wheel revolves, an actuator activates the light at a predetermined point. The actuation may be physical or electromagnetic in nature. The actuation triggers the lighting of light contained in the lighting mechanism. The light beams may emanate parallel to the path defined by the spokes, or perpendicular to the emanating spokes. To an observer from the front, the light travels downward over the effective wheel height, transforming the light into an elongated light source equal to the wheel height. The rate at which the light source travels downward gives rotational information. The lighting may be for a predetermined time. Or, either of the lights may be strobed. A timing circuitry sensitive to rotational information allows the lights to be switched on and off at predetermined times and/or points in the revolution of the wheel. Delays may be introduced, and strobing effects may be also introduced. In an exemplary aspect, the strobe rate may set at a rate proportional to the revolution rate.
