<p>A headlight for an automotive vehicle has a reflector which is formed in a substantially semicircular shape (2a) above the optical axis (A) of the headlight so as to serve as its reflective portion, an upper portion (2b) of the reflector which extends forwardly from the reflective portion serving as a light shielding portion and another light shielding portion (2c) provided below the lamp bulb (3), which is included in the headlight, and arranged substantially parallel to the optical axis (A). An upper lens element (8) of the lens of the headlight has a refractive index determined in such a manner that the rays of light incident upon the upper lens element from the reflective portion (2a) of the reflector are widely refracted downwardly, and the vertical dimension of the lower lens element of the lens of the headlight is reduced by a distance (L') as compared with a conventional headlight to provide a reduction in the vertical dimension of the headlight without substantially reducing its performance.</p> |
