Indicator lamp with simplified optical structure

An indicator lamp for a motor vehicle, comprising:

• a plurality of light sources;
• a plurality of linking elements;
• and
• optical processing means for straightening out the light emitted by the light sources so that the light is propagated in a direction essentially parallel to a general direction of emission;
• wherein the optical processing means comprises a plurality of first elements, each first element corresponding to one of the plurality of light sources, and a second element;
• wherein each of the first elements includes a plurality of striations, the first elements adapted to distribute the light in a plane essentially perpendicular to the general direction of emission in an essentially uniform way onto the second element;
• wherein the second element is adapted to straighten out the light towards the general direction of emission;
• wherein the plurality of linking elements are arranged between the first elements that are adjacent, and between the first elements and the second element, and wherein the first elements, the second element, and the linking elements are made together of the same material and form a one-piece optical structure.
