Abstract
A scanning light source includes a light source, and scans the output light of the light source ahead of a lamp. A control apparatus controls the lighting on/off state of the semiconductor light source in synchronization with the scanning operation of the scanning light source. The control apparatus judges the presence or absence of an abnormal state with at least one from among (i) a timing immediately before switching from a lighting-on state to a lighting-off state and (ii) a timing immediately before switching from a lighting-off state to a lighting-on state as a judgment timing.
