The invention relates to a headlight for vehicles comprising a plurality of groups (4, 5, 6) of LED light sources and comprising a plurality of optical units (1, 2, 3) having different imaging characteristics, such that first light spots (L1) imaged by a first optical unit (1) have a different size (h1, h2) with respect to second light spots (L2) imaged by a second optical unit (2), wherein a first partial light distribution (FL1) is formed by the first light spots (L1) and a second partial light distribution (FL2) is formed by the second light spots (L2), and wherein the groups (4, 5, 6) of LED light sources can be driven in such a way that a predefined total light distribution is formed by the superimposition of the partial light distributions (FL1, FL2, FL3), wherein the optical units (1, 2, 3) are embodied in such a way that all the light spots (L1, L2, L3) have an identical width (b) and that the light spots (L1, L2, L3) imaged by different optical units (1, 2, 3) have a different height (h1, h2, h3).
