To provide a vehicular headlight allowing the vertical size of a spring member in the front view to be reduced, and allowing the vertical size of the whole headlight to be reduced as compared with a conventional headlight where the posture of a shade is changed over in the vertical direction because the posture of the shade is changed over between an obliquely upper rearward direction and an obliquely lower frontward direction.

The posture (position) of the shade 6 is changed over between a low-beam posture on the obliquely upper rear side and a high-beam posture on the obliquely lower front side by a spring member 6 and a solenoid 7. As a result, the vertical size of the spring member 6 in the front view can be reduced as compared with a conventional vehicular headlight where the posture of a shade is changed over in the vertical direction. Thereby, the vertical size of the whole headlight can be reduced as compared with the conventional vehicular headlight.
