Abstract

The invention relates to a lighting device for vehicles that envisages a light-decoupling element in a decoupling bay of the vehicle. The light-decoupling element is fed by a light source arranged at a distance therefrom. A light guide is envisaged between the light source and the light decoupling element. An additional decoupling bay lighting device is envisaged to achieve a visually appealing appearance of the decoupling bay and to illuminate the decoupling bay of the light-decoupling element.
