1. An automobile headlight comprising:

  • a light source;

    a movable shade positionable between a traveling position P and a by-passing position Q, when the automobile is traveling straight ahead and when by-passing another vehicle, respectively;

    a reflector having a by-passing reflecting portion that reflects light emitted from the light source downward to form a light distribution pattern for by-passing, and a traveling reflecting portion which reflects light emitted from the light source when the movable shade is in the position P for traveling straight ahead, the by-passing reflecting portion positioned adjacent the traveling reflecting portion;

    a fixed shade which directs light emitted from the light source towards the reflector, the fixed shade positioned adjacent the light source; and

    a driving unit connected to the movable shade for changing a position of the movable shade, wherein;

    the movable shade in the by-passing position Q suppresses light emitted from the light source towards the traveling reflecting portion and passes light emitted from the light source toward the by-passing reflecting portion; and

    the movable shade in the traveling position P partly suppresses emitted light at an upper end of the by-passing reflecting portion and passes light emitted from the light source toward the traveling reflecting portion and the remaining by-passing reflecting portion.
