An exterior lighting system of a motor vehicle (10) has headlamps (12) and foglamps (14) for illuminating a field of view. The headlamps have lenses (26) through which light passes to illuminate the field of view and are constructed to alter the light that is directed within the headlamps toward upper zones (26A) of the lenses relative to light that is directed toward lower zones (26B) of the lenses when both headlamps and foglamps are shining onto the field of view so as to attenuate headlight glare that would otherwise be seen by a driver of the vehicle looking toward the field of view in the absence of the light alteration. Various embodiments of inventive headlamps are shown.
