  • Patent number: 6547424
    Abstract: A front lamp steering controlled light distribution system is disclosed having a light distribution means movable to vary a light distribution pattern to right and left maximum limit positions in cornering areas of a vehicle, and a control means responsive to a turned on state of a head lamp switch for actuating the light distribution means to cause the light distribution pattern to be varied according to a steering direction signal, indicative of an incremental steering angle of a steering wheel, in the absence of a vehicle speed signal, indicative of a vehicle speed less than a given value, and operative to drive the light distribution means to cause the light distribution pattern to be fixedly directed to the maximum limit position in response to an indicator direction signal, output from a blinker condition detection means (14), in the presence of the vehicle speed signal.
