Stromes one for the lighting of the on-board devices resp. the dashboard "intended light source,

This object is achieved according to the invention by that the light from the light source is passed through a see-through cap consisting of a dumbbell surface and a front surface and alternately the Maatelfläohe is left exposed or old an »opaque object is covered.

An advantageous device for carrying out the process according to the invention has, according to the invention, a holding tube set on the socket of the light source, onto which a translucent cap consisting of a jacket surface and an end surface is fitted, with an opaque cover tube adjacent to the jacket surface being able to be pushed onto the cap is. If the cover tube is not pushed over the cap, the cap emits light on all sides and illuminates the whole area, that is, for example the whole dashboard or another larger area which should be illuminated. When the cover tube is pushed onto the translucent cap, there is almost dmt total luminous flux out of the front surface of the translucent cap and it can be a gesielte illumination of a particular object, for example a

certain section of the on-board devices or the dashboard, to achieve.

Using the figures, the invention is explained in more detail, for example. It shows

FIG. 1 shows a schematic section through the elements according to the invention Device with the cover tube removed and

Figure 2 shows a section corresponding to Figure 1 with Aufce * pushed a cover pipe.

An elastic sealing ring is attached to a holding plate 1 and comprises a lamp holder k inserted into the base plate. An inwardly protruding flange of a holding tube 3 is pressed into the elastic ring 2 by the front, upturned edge 9 of the mount k, so that a sealing void is created on its edge. On the outer surface of the holding tube 3 is an elongated, consisting of jacket surface 11 and front surface 12, through *

As a light source, the luminous flux occurs on all sides according to the arrows 7 from the jacket surface 11 and the end surface 12 of the cap 5 the end. This arrangement is well suited for illuminating a larger area.

In contrast, if a small section, for example a best inmtes instrument be selectively illuminated, as an opaque cover tube 6 is pushed onto the circumferential surface 11 _r ο that the light tr o "only" ore in the direction of the arrows 8 by the end face. 12 of the cap 5 can occur.
