Abstract
A lighting apparatus for vehicles with a housing sealed by a transparent covering panel, containing a light source unit and an optical unit for producing a predetermined light function, wherein the optical unit has a hologram element and/or diffractive element in which diffraction information for producing the light function is contained, wherein optics are disposed downstream of the hologram element and/or the diffractive element in the light beam path, so that light of different orders of diffraction emerging from the hologram element and/or the diffractive element produce different light functions.
