<p>PURPOSE: To prevent a delay of recognition by an opposite vehicle during a temporary stop under a right turning and an emergency stop and erroneous recognition of an own vehicle running intension by a method wherein an extinction control means prohibits an output of an extinction command during input of a right turn signal from a right turn signal detecting means. CONSTITUTION: An extinction controller 7 detects it based on a signal from the output terminal 51 of a light-ON and OFF controller 5, driving a head light relay 2, that external illuminance from a photo sensor 6 is low illuminance, and turns on and off a built-in output switch 70 when it is detected from a car speed signal Sv from a car speed sensor 8 that a vehicle stops. The extinction controller 7 reads a right turn signal lighting-on lamp signal Sr, being a signal voltage inputted from the high order end of a right turn signal lamp 92, and further reads a car speed signal Sv based on a signal voltage from a car speed sensor 8. When a relay 2 is turned ON and low illuminance right turn signal lamp is under light-on, and in a stop state, the output switch 70 is turn ON and OFF in a given duty ratio, and an incandescent lamp 72 is turned ON.</p> |
