ABSTRACT:
A low beam light distribution pattern is formed by turning on a first light source unit and a high beam light distribution pattern is formed by additionally turning on a second light source unit. The second reflector of the second light source unit has reflecting faces of vertical cross-sectional shapes formed by two types of ellipses whose first focal point is on a center of emission of a second light-emitting element and whose second focal points are respectively positioned on points A, B. The additional lens whose rear focal points are on the second focal points A, B is arranged on a circumference of a projection lens. When the second light source unit is turned on, a high beam additional light distribution pattern is formed that vertically strides over the cutoff line of the low beam light distribution pattern.
