Abstract
A device for motor vehicles is proposed which comprises a pictograph which is disposed in an at least partially transparent device part, can be optically highlighted by light beams and is produced by means of a process of influencing the material of the device part in a mechanical manner. In order to form three-dimensional pictographs in any color, the pictograph is produced in the material of an originally homogenous component of the device part and the pictograph is allocated a light coupling-in site, which is located on a lateral region of the component, in such a manner that the pictograph is at least partially captured and illuminated accordingly by the light beam bundle which is coupled via said light coupling-in site into the component.
