Abstract:
A vehicular lighting device includes a scanning light source. The scanning light source includes a semiconductor light source, and scans the output light of the semiconductor light source in a forward region ahead of the lighting device. A lighting circuit changes the light amount of the semiconductor light source in multiple levels in synchronization with the scanning of the scanning light source.
