PURPOSE:To prevent the repetition of unwilling lighting-on and -off when a vehicle advances and stops, repeatedly at low speed, by inhibiting head-lights from being lit on until the vehicle runs at a constant speed. CONSTITUTION:A control part 14 controls the lighting-on and -off of head-lights in accordance with the outputs of an illuminance sensor 1, a running sensor 2 and a throttle sensor 3, and is connected with memories 18A, 18B utilizing, writable and readable RAMs, etc. Data written on the memories 18A, 18B are used as control data for the control of lighting-on and -off, and therefore, the control part 14 issues an output to light on the head-lights when all of the data on the memories 18A, 18B are ''1'', but issues an output to light off the head- lights when at least either one of the memories 18A, 18B is ''0''. |
