The light shielding member (shade) is disposed such that a light shielding reference point coincides with a lamp unit axis. The light sources are disposed with an emission light axis positioned above the lamp unit axis in the vertical direction. The condenser lens is disposed such that condenser lens axes are positioned above the lamp unit axis in the vertical direction.
