ABSTRACT:
The improved vehicle headlight has both leveling device and beam switching device which drives bulb displacing mechanism to displace light source bulb relative to reflector along its optical axis. In addition to driving the bulb displacing mechanism to displace the light source bulb relatively in a determined amount, actuator of the leveling device is driven to tilt the reflector through a determined angle, whereby a low beam is switched to a high beam and vice versa. Compared to the conventional system that performs beam switching by merely driving the bulb displacing mechanism, the vehicle headlight enables the same bulb displacing mechanism to displace the light source bulb through simple relative movements.
