A head lamp unit includes two lighting fixtures, each of which includes a running beam filament and a passing beam filament, for selectively producing a running light beam and a passing light beam. The light distribution characteristic of the passing light beam of one of the lighting fixtures is arranged to be symmetrical to the left and right, whereas the light distribution characteristic of the passing light beam of the other lighting fixture is arranged to be asymmetrical to the left and right, to thereby provide an improved passing light beam.
