Claim 0:
1. A signal light device of a motor vehicle designed to fulfil one or more signal light functions, comprising a housing covered by transparent or translucent cover which separates and protects the signal light device from external surroundings of the motor vehicle, an internal chamber delimited by the housing and the cover, and at least one signal lighting unit, wherein the signal lighting unit comprises:
(i) a carrier with a supporting surface to which at least one light source is attached to emit light rays,
(ii) a front panel, one of which surfaces faces the cover and the other surface is opposed to the supporting surface, and
(iii) a thin-walled partition panel situated between the supporting surface and the front panel and at a distance from them,
wherein the thin-walled partition panel comprises an input surface facing the supporting surface and an output surface opposite the input surface,
wherein the supporting surface is fitted with a main reflective surface to reflect light rays,
wherein the space between the front panel and the output surface and between the supporting surface with the said at least one light source and the input surface is filled with air,
wherein the thin-walled partition panel is, in the region situated opposite the at least one light source, fitted on its input surface with a first arrangement of discrete first reflective surfaces and first gaps between the first reflective surfaces, and on its output surface with a second arrangement of discrete second reflective surfaces and second gaps between the second reflective surfaces,
wherein the first and second reflective surfaces are configured to reflect light rays and the first and second gaps are configured to transmit light rays, and
wherein the first arrangement of reflective surfaces and the second arrangement reflective surfaces are configured to achieve a pre-determined intensity distribution of the output of light rays from individual places of the output surface of the thin-walled partition panel.
