A headlight for vehicles has a bowl-shaped reflector (1), between which and a lens (2) a first (3) and a second (4) adjustable diaphragm is arranged. The second diaphragm (4) is arranged above the first diaphragm (3) and has an axis of rotation (5) which runs horizontally and transversely to the optical axis (6). The aperture (4) can be adjusted in several rotational positions about the axis of rotation (5) and has at least two different focal lines (7, 8, 9).
