<p>PURPOSE:To prevent the inutile consumption of a battery by installing a signal generator for flashing a hazard flasher lamp for a certain time by the light receiving signal of a light receiving element which receives the light of a headlight. CONSTITUTION:When a light receiving element 1 receives the light signal of a headlight which is over a set luminous intensity, the output of an off-delay timer part B operates a flashing signal generation part C by a multivibrator at the same time, and a hazard flasher is flashed through an amplification part D consisting of a transistor and a relay. When the luminous intensity of the received light becomes less than a set value, the flashing of the hazard flasher is delay for a certain time by an integration circuit of the delay timer part B, and operation stops.</p> |
