Left and right lighting devices (30) illuminate a region containing a part above a cutoff line of a low-beam light distribution pattern. A high-beam formation shade provided in each lighting device (30) shades a part of light emitted from a light source (86) in each of the left and right lighting devices (30), and thereby forms a right side light distribution pattern (RP) or a left side light distribution pattern (LP) having a non-perpendicular cutoff line (RC, LC) above the horizontal line (H-H). A vehicle position detecting section (52) detects a position of a vehicle in front of the own vehicle. A cutoff line position determination section (54) determines a horizontal positions of the non-perpendicular cutoff lines (RC, LC) such that an overall light distribution pattern generated by superposing the right side light distribution pattern (RP) with the left side light distribution pattern (LP) should have a shaded region in accordance with the vehicle position detected by the vehicle position detecting section (52). |
