System and method for exterior lighting of vehicles

A vehicle fog lamp comprising:

• an aspheric projection lens having a back focal point and an optical axis passing therethrough;
• a reflector having a plurality of ellipsoidal facets, the reflector disposed on a back side of the projection lens above a plane containing the optical axis, each facet having corresponding first and second focal points, the plurality of first focal points contained within a first focal region of the reflector and the plurality of second focal points contained within a second focal region of the reflector;
• a semi-conducting light source, the light source disposed on a reflector side of the back focal point of the projection lens and facing generally away from the projection lens and toward the reflector, the light source being disposed at an acute angle relative to the optical axis within the first focal region of the plurality of reflector facets;
• and
• a shade curving away from the projection lens and having an apex with an upper edge of the apex disposed within the second focal region of the reflector, the shade disposed between the projection lens and the light source and blocking a portion of light reflected from the reflector to create a beam pattern cutline.
