ABSTRACT:
The headlight apparatus has at least one headlight unit which includes several headlight subunits (20;40;60; 61;70;90). A base low beam which illuminates a base region in front of the vehicle is produced by at least one of the headlight subunits (20;40) in such a way as to fulfill the basic minimum requirements for a low beam. Additional headlight subunits (60;61;70;90) are connectable to the headlight subunit (20;40) producing the base low beam. At least one of the headlight subunits (20;70) is constructed according to the projection principle and has a reflector, a light source and, following the reflector, a lens and a diaphragm. At least one of the headlight subunits (40;60;61) is constructed according to a reflection principle and has a reflector, a light source and, if necessary, a light permeable disk with optical elements in it. A concentrated or focused light beam is produced by the headlight unit or units (20;70) constructed according to the projection principle while a horizontally scattered light beam is provided by the headlight subunit or subunits constructed according to the reflection principle.
