Abstract
A light distribution control device controls formation of a light distribution pattern by a light distribution variable lamp. The light distribution control device controls the light distribution variable lamp so as to reduce an illuminance of light that illuminates a non-traveling road when a vehicle reaches a first location a predetermined distance before a forked road, while a normal light distribution pattern is formed that includes, in an illumination range thereof, a side illuminating a traveling road of the vehicle at the forked road and a side illuminating the non-traveling road, and to form a guiding light distribution pattern in which an illuminance of light that illuminates the traveling road is higher than the illuminance of the light that illuminates the non-traveling road.
