ABSTRACT:
The invention relates to a headlight for a motor vehicle, to a lamp for the headlight, and to a headlight unit. The lamp has two coils and is capable of fulfilling widely differing functions. Means for screening off the light emitted by the coils in certain angular regions are arranged such that the regions illuminated by the coils overlap only slightly, preferably not at all. At least two reflector regions of the lamp are each illuminated by an associated coil, and are shaped such that one headlight emits two headlight beams, both having a substantially horizontal bright/dark cutoff.
