There are provided five first lighting units for carrying out light
irradiation to form a horizontal cutoff line. Each of the first lighting
units has such a structure that includes a first light source formed by a
light emitting diode provided to face forward in such a manner that one
side of a rectangular light emitting chip is extended in a horizontal
direction, and first projection lenses provided in front thereof and
serving to project the image of the first light source as an inverted
image forward from the lighting units. Consequently, the inverted image
of the first light source projected forward from the lighting unit is an
almost rectangular image having an upper edge extended almost
horizontally. These are provided with a shift from each other in the
horizontal direction, thereby forming a horizontal cutoff line. Two
additional rows of lighting units provide light for an oblique cutoff
line and a diffuse light pattern, respectively.
