A light distribution control apparatus which is less affected by an error in a navigation function, and conducts a proper light distribution. An illuminated area and a glare quantity are controlled according to a determination on a traveling region of a vehicle (an expressway, a general road, or an urban region), and an illuminating direction is controlled according to a determination on a road shape. On the other hand, a navigation processor determines reliabilities of current position detection, and a vehicle position based on road data, and determines a reliability of the road shape and a reliability of the traveling region. A base illuminated area and a medium glare are selected when the reliability of the traveling region is low, an illuminated area according to the traveling region is selected and the glare quantity is decreased when the reliability is medium, and an illuminated area and a glare quantity according to the traveling region are selected when the reliability is high. A light distribution angle theta hs according to a steering angle is selected when the reliability of the road shape is low, and a light distribution angle theta hn for illuminating a vehicle position after T seconds is selected when the reliability is high.
