PURPOSE:To prevent emission of a dazzling light to an opposite car, by a method wherein, when a distance detected by an opposite car distance detecting means and a distance computed by an irradiation distance computing means based on a running speed are brought to a relation in which a dazzling light is emitted to an opposite car, an irradiation distance is decreased for correction. CONSTITUTION:When a light switch 1 is turned ON with an auto switch 3 turned ON, a head light controller 6, consisting of a microcomputer, conducts a short distance irradiation through a near lighting-ON driving circuit 8. When a charge-over switch 2 is switched to the distance side, with an optic axis angle regulator 10 brought to a maximum irradiation range, a distant light is also lighted ON by means of a distant lighting-ON driving circuit 9. A radar device 5 detects an opposite car, and when a distance thereof is within an irradiation distance found from a car speed detected by a car speed sensor 4, through operation of a distant light optic axis angle regulator 10, the irradiation distance of a distant light is decreased for correction so that and opposite car can not suffer from a dazzling light. |
