Abstract: An array of randomly flashing warning lights comprised of high intensity Light Emitting Diodes, alert observers to the presence of moving vehicles or pedestrians. Motion sensors such as tilt, reed, or mercury switches can be used to achieve randomized flashing while vehicle or pedestrian are in motion. Dynamic forces, generated by motion, cause sensor contact closures which, in turn, produce short duration pulses of light to be emitted by the LED array. When motion ceases, an auxiliary circuit automatically causes the LED array to continue flashing for a period of about one-minute. The extended period of flashing will continue to alert observers should the vehicle or pedestrian stop for a traffic light, stop sign, or sundry other reasons. Termination of the warning light's activity will result in a power-down state wherein power consumption becomes so minute it eliminates the need for an on-off switch.

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.

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.
