Abstract
An automobile headlight including a single movable light source which does not change the angle of its optical axis relative to the optical axis of the reflector. The light source is coupled to an apparatus capable of changing the position of the light source depending on the driving state of the automobile. The headlight has sufficient light distribution patterns for multiple driving conditions, such as when the automobile is traveling straight ahead, by-passing another vehicle, or carrying a heavy load, without changing the angle of the optical axis of the light source relative to the optical axis of the reflector. This allows the driver to maintain good visibility while prolonging the life of the headlight and reducing its overall size.
