A vehicle lamp emitting light to a lateral direction can include a simple construction
to reduce design limitations, and can achieve desired light distribution characteristics
by controlling the direction and intensity of light illuminated in a range covering
the front and the side of the vehicle. The vehicle lamp preferably includes: a
second reflecting surface for reflecting incident light from a light source to
a predetermined direction; a third reflecting surface, arranged forward of the
light source and backward of a projection lens and out of a main optical path,
for reflecting light from the second reflecting surface toward front; and a fourth
reflecting surface, arranged forward of the third reflecting surface and out of
the main optical path, for reflecting light from the third reflecting surface to
a lateral direction relative at least to a region of light emitted from the projection
lens along the main optical path.
