Abstract
A headlight has a plurality of lighting device units and a unit support member that supports the plurality of lighting device units. Each lighting device unit has a projection lens, a light emitting diode arranged behind a rear side focus of the projection lens, and a rectilinear propagation blocking member that is arranged in a vicinity of the rear side focus, and blocks a rectilinear propagation of a portion of light emitted from the light emitting diode so as to form a cutoff line. The projection lens and the rectilinear propagation blocking member are integrally formed as a light control member in each light device unit.
