 of such prior devices are those safety lights disclosed in U.S. Pat. Nos. 4,423,473 and 4,451,871. In these devices, a penlight battery power supply is coupled to an ordinary LED mounted within a lensed reflector housing by means of a position sensitive mercury switch, so that, when the device is worn or carried, the position sensitive switch will on account of sensing the wearer's movements connect power to the LED to cause intermittent bursts of light to be emitted thereby. It is described that because power is supplied only intermittently to the LED, the light source LED may be operated from a battery source which provides current to the light source LED in excess of its maximum current rating to provide light of greater intensity than is normally producible from such light source (i. e. an ordinary low luminosity LED). Such a device however does not produce flashes at any particular effective flash rate (apart from being responsive to the rhythm of the wearer's motions sensed thereby), nor of any particular flash duration and thus is not optimal for attracting attention, nor reliable since it regularly will subject the LED to an overcurrent condition which while perhaps brief risks damaging the LED junction nevertheless should the mercury switch connection remain on for too long. Another motion-switched intermittently flashed safety light device is disclosed from U.S. Pat. No. 4,535,392.
In U.S. Pat. No. 4,523,258 there is disclosed a safety belt with flashing LEDs for joggers in which an array of LEDs arranged along a reflective belt are connected to a battery-powered oscillator circuit including two separate oscillators, one oscillating at &lt;1 to 5 Hz, and another oscillating at 3 Hz. Sets or subsets of the LEDs in the array are alternately driven by connecting these oscillators to opposite nodes of the array, such that one oscillator forwardly biases the LEDs and the other oscillator reversely biases the LEDS, such that LEDs of different sets are driven only when forwardly biased and thus flash alternately. However, such a device is only suitable for low ambient light conditions.
In U.S. Pat. No. 4,819,135 there is shown a bicycle lighting device in which strings of LEDS are mounted along the frame tubes of a bicycle and flashed in sequence to provide a broadside flashing triangular slow moving vehicle signal to motorists.

In these device, a penlight battery power supply is couple to an ordinary LED mount within a lensed reflecting telescope housing by means of a position sensitive mercury switch, so that, when the device is wear or carried, the position sensitive switch will on account of sensing the wearer's drift connect power to the LED to induce intermittent bursts of light to be emit thereby. It is described that because ability is supplied only intermittently to the LED, the light source light-emitting diode may be operated from a battery source which provides current to the light source head in excess of its maximum current rating to provide light of greater intensity than is normally producible from such light source (i. e. an ordinary abject luminosity LED). Such a device however does not produce flashes at any finical effective flare rate (apart from being responsive to the cycle of the wearer's motions sensed thereby), nor of any particular flash duration and therefore is not optimal for attracting attention, nor reliable since it regularly will subject the LED to an overcurrent condition which while perhaps brief risks damaging the LED articulation nevertheless should the mercury substitution connection remain on for too long.
