A pair of a white LED light source 25 and a selective yellow LED light source 26 is provided on LED mounting face portions 21 located on both sides of a light source heat conduction portion 23. The selective yellow LED light source is mounted on an upper side of the white LED light source so that the selective yellow LED light source and the white LED light source are substantially in contact with each other in a vertical direction, and the selective yellow LED light source is mounted on a rear side of the white LED light source so that a distance between the selective yellow LED light source and the white LED light source in a front-rear direction is equal to or shorter than the width of the selective yellow LED light source and equal to or shorter than the width of the white LED light source.
