Abstract
When occurrence of a failure associated with light distribution control has been detected during high beam irradiation, a low beam irradiation direction is changed upward and then the high beam irradiation is stopped, and subsequently the low beam irradiation direction is gradually returned downward. The time during high beam irradiation includes the time during which variable high beam light distribution control in which part of high beam light is shielded by a shade is being executed.
