Abstract

A lighting device for vehicles having a first light source, a second light source and a light-shaping apparatus allocated to the first light source and the second light source, wherein the second light source is offset in relation to the first light source, at least in a direction running perpendicularly to the optical axis of the light-shaping apparatus. The light that is incident on the light-shaping apparatus from the first light source is deflected to produce a first light function and wherein the light that is incident on the light-shaping apparatus from the second light source is deflected to produce a second light function, wherein the light-directing surface of the light-shaping apparatus has a free-form surface comprising multiple varyingly curved surface elements.
