Abstract:
1. An automotive vehicle comprising: a headlamp system comprising one or note low-beam headlamps for providing low-beam illumination of a forward field of view; each headlamp comprising a housing containing an internal light source and a lens through which light originating at the light source passes for low-beam illumination of the field of view; one or more foglamps for illuminating the field of view; a switch that is selectively operable to turn the one or more foglamps on and off; the one or more one headlamps comprising a selectively operable device whose operation is slaved to the one or more foglamps to act, when the switch turns the one or more foglamps on, upon light that is directed from the light source within the housing toward an upper zone of the lens relative to light from the source directed toward a lower zone of the lens below the upper zone so as to thereby attenuate headlamp glare interference with a driver's view of a road surface being illuminated when the one or more headlamps and the one or more foglamps are both on in comparison to glare that would be present in the absence of the selectively operable device acting to attenuate the glare, and to not attenuate headlamp glare interference with a driver's view of a road surface being illuminated when the switch turns the one or more foglamps off.
