1. A lighting device for a motor vehicle, the lighting device comprising:
a light source;
a light guide with an entrance surface; and
a hologram disposed on or in the light guide;
wherein the lighting device is configured such that light emanating from the light source enters the entrance surface of the light guide and interacts with the hologram so that an image stored in the hologram is reconstructed and is visible to an observer of the lighting device,
wherein the light guide has a first exit surface and a second exit surface, such that the light entering the entrance surface of the light guide exits from both of the first exit surface and the second exit surface,
wherein the lighting device is configured such that light that has interacted with the hologram exits through the first exit surface, the light interacting with the hologram either during the exit or after the exit from the first exit surface, and the lighting device is configured such that light that has not interacted with the hologram exits through the second exit surface, the light not interacting with the hologram either during the exit or after the exit from the second exit surface.
