In the projector-type head lamp for vehicles according to the present invention, a discharge lamp having a single color temperature is disposed at one of the foci of the inside reflective surface of a predetermined geometrical shape. There is disposed at the other focus of the inside reflective surface a shade intended to shape the reflected light beam from the inside reflective surface. The light beam having been shaped into an appropriate shape by the shade is condensed and projected frontward through the lens. Since the light source is a discharge lamp having a single color temperature, these light beams cause no dispersion by the lens. Therefore, no colored zone is produced near the dark area of the luminous intensity distribution pattern projected frontward, that is located along the light-dark limit defined as the result of the cutting by the shade of the light beams.
