A lighting device for vehicles with a first lighting unit having a light source and a light beam surface for emitting light and with a second lighting unit containing a light source and a flat light guide having opposite flat sides and narrow sides connecting the same for backlighting the first lighting unit. The flat light guide of the second lighting unit has a backlighting section and a linear light section. The backlighting section is arranged behind the first lighting unit and a front flat side of the flat light guide in the backlighting section serves as a light decoupling surface for the light decoupling of a first part of the light coupled into the flat light guide. The linear light section is at least partially arranged next to the first lighting unit. A narrow side of the flat light guide serves as a light decoupling line.

A directional illumination device for a vehicle external light comprises an array of light sources and an imaging waveguide comprising an input surface and a reflective end. Opposed guide surfaces are arranged to guide input light from the input surface to the reflective end and back along the waveguide after reflection at the reflective end, the waveguide being arranged to extract input light as it is guided back along the waveguide after reflection and to cause the extracted light to exit through the first guide surface. The reflective end has positive optical power in the direction laterally across the waveguide and the waveguide is arranged to direct the extracted light in respective output illumination directions distributed in a lateral direction in dependence on the input positions of the light sources in the direction laterally across the waveguide. A thin, high brightness and high efficiency controllable directional vehicle headlight is provided.
