The invention concerns a head-lamp with an integrated microwave antenna, the head-lamp comprising a rotationally symmetrical paraboloidal reflector (21) and the microwaves being radiated in a directly lateral manner. To that end, an electrical feed element (15) is disposed laterally of the reflector (21) and at a suitable spacing in front of a light source (13), viewed in the radiation direction (14). The microwave system feed element (15) is arranged such that the radar beam is directed through the upper half of the reflector and focused. The beam path for the light source is represented by the marginal rays (131 and 132). The beam path for the microwave system feed element (15) is represented by marginal rays (151 and 152). According to the invention, the optical system with its light source (13) and the microwave system with its feed element (15) and/or receiver element are designed operationally and spatially such that they are completely independent of one another and are disposed separately. The two systems, each configured separately from the other in optimum manner, can then be fitted jointly in the common housing for the head-lamp.
