ABSTRACT:
An improved headlight having variable light distribution is provided, where said headlight comprises a reflector divided into an upper movable light distribution reflector and a lower fixed light distribution reflector by a horizontal line located 10 to 30 mm above the optical axis of the light source and the reflector, of which said movable light distribution reflector is rotatable around a vertical rotary axis practically crossing the optical axis of the light source and said fixed light distribution reflector is designed to reflect 50 to 60% of the total quantity of light applied to the reflector. With such an arrangement, the swerving side of the automobile is satisfactorily illuminated by the movable light distribution reflector while a desired frontal light distribution pattern of the headlight is ensured by the fixed light distribution reflector because the two reflectors provide a substantially equal quantity of light.
