Abstract

The headlight has a gas discharge lamp and a reflector. The reflector has an upper reflector region and a lower reflector region. A lens is arranged after the reflector in a light outlet direction, and a screen device is provided between the reflector and the lens. A movable screen member of the screen device is adjustable between a position for low beam in which it screens light reflected from the lower reflector region and produces a bright-dark limit, and a position for high beam in which light reflected from the lower reflector region passes past the screen member and can exit the headlight. Moreover, the movable screen member in its position for low beam is adjustable between a position for right traffic and a position for left traffic. Therefore the head light can be used in a simple manner as a high beam head light and a low beam head light, and also can be converted for the utilization for right traffic and left traffic.
