Abstract
An indicator lamp for a motor vehicle includes a plurality of light sources, and a plurality of linking elements. The lamp includes components that straighten out the light emitted by the light sources so that the light is propagated in a direction essentially parallel to a general direction of emisssion. These components include multiple first elements and a second element. East first element corresponds to one of the plurality of light sources. The first elements are able to distribute the light in a plane essentially perpendicular to the general direction of emission, in an essentially uniform way onto the second element. The second element is able to straighten out the incident light towards the general direction of emission.
