Abstract
A vehicular lighting device includes a scanning light source that includes a semiconductor light source and a motor, and scans a region in front of the lighting device, with light emitted from the semiconductor light source, in accordance with motion of the motor, and a lighting circuit that changes the light quantity of the semiconductor light source in synchronization with the motion of the motor, during a normal lighting period, so as to obtain a predetermined light distribution pattern. The lighting circuit starts the motion of the motor, in response to a lighting command for headlight flashing during a stop period of the motor, and continuously lights the semiconductor light source asynchronously with the motion of the motor, during a start-up period that precedes the normal lighting period.
