ABSTRACT:
The warning light system comprises a high-intensity, electronic flash lamp used in combination with a highway vehicle's conventional brake, turn signal, and emergency flasher light assemblies. The electronic flash lamp comprises a gas-filled lamp discharged across capacitors operating at about 800 to several thousand volts D.C. The flash lamp circuitry is tied into the existing brake light switch such that the capacitors will be discharged in response to actuation of the brake assembly when the brake initially is applied and the capacitors will not be discharged again until the brake assembly is actuated again. The resultant high-voltage pulse initiates a brilliant flash which lasts micro-seconds and which warns following drivers of an impending vehicle stop or slow-down. The high-intensity flash lamp circuitry also is tied into the turn signal and emergency flasher light assemblies so that a more positive indication of an impending turn or emergency is provided.
