Abstract
A vehicle headlight includes a driving unit capable of repeatedly switching the headlight's light distribution pattern between a by-passing mode and a traveling mode by moving an element committed to the formation of the light distribution patterns. The driving unit includes a first spring for biasing a positioning element in a by-passing mode, a meshing gear for moving the positioning element to a traveling mode position against the bias of the first spring, a motor which supplies power to drive the meshing gear, a second spring biased in an engaging direction of the meshing gear, a solenoid for releasing the engagement of the meshing gear with a second gear against the pulling power of the second spring. The disclosed headlight enables size reduction of the driving unit, and provides improved reliability if the motor malfunctions.
