ABSTRACT:
A head lamp (3) is turned off when a first set time (T1) has lapsed in a state that a circumferential illumination intensity (B) is equal to or higher than a first level (B1), or when the vehicle has run a first set distance (L1) in a state that the circumferential illumination intensity (B) is equal to or higher than a second level (B2) lower than the first level (B1). Accordingly, even if the vehicle is stopped immediately after a moving to a bright place from a dark place, or even if the peripheral environment has become bright during a stop in the dark place, the head lamp (3) can be securely turned off.
