Vehicle signal lighting unit
 A vehicle signal lighting unit includes a light source, a plain outer lens, and a composite reflecting mirror consisting of a unit reflecting surface which reflects light having desired light distribution characteristics from the light source. The light source emits no direct light in an illuminating direction of the vehicle signal lighting unit, and is positioned to allow incident light against said composite reflecting mirror from at least two directions, and to prevent direct observation of the light source itself through the outer lens. Each unit reflecting surface of said composite reflecting mirror includes reflecting surface which reflects light from the light source from said two directions. Since the light source is provided outside an effective luminescent surface, the light source cannot be observed directly from outside through the plain outer lens. The light source can be mounted on both ends of the lighting unit outside an effective luminescent surface. The outer lens side of the light source can be provided with a hood member for preventing observation of the light source itself.
