A lamp including a light source, a petaline reflector, and aspheric lenses. The petaline reflector is formed of a plurality of reflecting surface units combined radially around the center axis of the light source. Each of the reflecting surface units is obtained by cutting, radially around the center axis, a portion from a spheroid having a first focal point located on the center axis and adjacent the light source and a second focal point located on a line passing through the first focal point and tilted appropriately from the center axis such that the cut portion spans a range of 15.degree. to 60.degree. around the center axis. The aspheric lenses are disposed to correspond to the respective second focal points of the reflecting surface units of the petaline reflector and converge reflected light beams from the respective reflecting surface units. Shades for forming a light distribution pattern are disposed at the respective near-focal points of the aspheric lenses.
