The invention concerns a light unit with at least one LED, including at least one light-emitting chip as light source, with primary optics that include at least one fiber-optic element, optically connected after the LED, and with secondary optics, optically connected after the fiber-optic element. For this purpose, the light unit includes a second LED with at least one light-emitting chip as light source. The primary optics includes a second fiber-optic element, optically connected after the second LED and optically connected before the secondary optics. The light outlet surfaces of the two fiber-optic elements are adjacent to each other at a partition.With the present invention, a light unit with high light output is developed, both for low beams and high beams, which requires limited space.
