Abstract

The headlight arrangement for a vehicle produces respective light beams with different characteristics and includes at least two headlight units (10), each having a number of individual headlights (12, 14, 16), by means of which the respective light beams are produced and operated simultaneously and/or in different combinations. The headlight unit (10) has at least one base headlight (12) by which a light beam with low beam characteristics is produced. In a basic or initial configuration the base headlights of two headlight units on opposite sides of the vehicle have substantially parallel optic axes (11) and their light beams are superimposed. The base headlights (12) may be pivoted in opposite directions from each other from their initial configuration about vertically extending axes (40) so that their optic axes (11) diverge or converge. The light beams produced by the base headlights (12) are no longer superimposed to the same extent so that lower intensities are provided in a central region in front of the vehicle but the illumination extends over a greater horizontal breadth in front of the vehicle when their light beams diverge. This is especially advantageous in city traffi…
