Abstract: High intensity light emitting diodes, visible even in daylight, provide observers with a distinct visual warning that a bicycle is in motion. This is accomplished using a magnet or series of magnets attached to one or both rotating wheels; said magnets being capable of actuating one or more reed switches. The reed switch contact is connected to an electronic circuit having power handling ability far beyond the capacity of the reed switch alone. Included in the circuit is a timing feature which limits the length of time the light emitting diodes are illuminated even if a magnet should maintain a reed switch continuously actuated. Major power drain occurs only during the flashing period of the light emitting diodes. Otherwise, power drain is of such low intensity that no shut off switch is needed; allowing the safety indicator to be active at all times. Both light intensity and flash duration are independent of a wheel's rotational speed or direction of rotation.
