A light device, especially a headlight of motor vehicles, comprises at least one light unit (1), or a group (1a, 1b) of light units, at least one optical directing element (3, 2e, 3f), adapted to direct the light beam emitted by the light unit, or group of light units, to the required direction, and at least one output lens (4) for passage of at least a part of the light rays of the light beam or beams to create a light pattern (A, B, C) on the display surface (ZY). On the route of the light beam between the optical directing element and the output lens, there is at least one optical diaphragm element (11, 21, 31) containing a system of trim edges (13, 23, 33) to create the required shape of the cross-section of a part or parts of the light beam designed for transmission along the above-mentioned route.
