Lamp arrangement comprising: • a flat light-guiding part having - a first light coupling portion, - a second light coupling portion different from the first light coupling portion and - a light outcoupling side provided on a flat side of the light-guiding part, • an optical element, which is partially in planar contact with the light outcoupling side, • a light exit surface provided on a side of the optical element facing away from the light outcoupling side and • light-guiding structures (3, 14, 15), which are disposed and designed such that they - do not optically influence light incident from the outside into the first light coupling portion, so that the light incident via the first light coupling portion exits the light-guiding part via the contact region between the light-guiding part and the optical element via the light outcoupling side and further exits the lamp arrangement outward via a first defined region of the light exit surface according to a first emission characteristic and - do optically influence light incident from the outside into the second light coupling portion, so that the light incident via the second light coupling portion exits the light-guiding part via the light outcoupling side and further exits the lamp arrangement outward via a second defined region of the light exit surface, which at least partially overlaps the first defined region, according to a second emission characteristic, wherein the light-guiding structures (3, 14) comprise • a reflecting portion disposed on a side of the light-guiding part facing away from the light outcoupling side and • optical deflecting structures which are designed and disposed in the flat light-guiding part such that light incident from the second light coupling portion (12, 13) is deflected toward the reflecting portion in such a way that the reflecting portion reflects the incoming, deflected light in the direction of the light outcoupling side so that the reflected light exits the light-guiding part outward via the light outcoupling side. • a flat light-guiding part having -
