Light emitting module for an automotive vehicle, comprising: - an optical part, comprising: - at least a first portion comprising a first light input face for receiving first light rays from a first light source and transmitting the first light rays directly toward a light output face so that the light exits the optical part; and - at least a second portion comprising a second light input face for receiving second light rays from a second light source and transmitting the second light rays toward said light output face so that they are reflected at least one time by total internal reflection on a first zone of said light output face before exiting the optical part through a second zone of said light output face, characterized in that the at least one second portion protrudes from the at least one first portion, the optical part comprising a plurality of first portions comprising each a first light input face and a plurality of second portions comprising each a second light input face; - a plurality of first light sources each opposite an associated first light input face of a first portion; - a plurality of second light sources each opposite an associated second light input face of a second portion; and - wherein each first light input face is associated to a first light source and each second light input face is associated to a second light source. - an optical part, comprising: - at least a first portion comprising a first light input face for receiving first light rays from a first light source and transmitting the first light rays directly toward a light output face so that the light exits the optical part; and - at least a second portion comprising a second light input face for receiving second light rays from a second light source and transmitting the second light rays toward said light output face so that they are reflected at least one time by total internal reflection on a first zone of said light output face before exiting the optical part through a second zone of said light output face, characterized in that the at least one second portion protrudes from the at least one first portion, the optical part comprising a plurality of first portions comprising each a first light input face and a plurality of second portions comprising each a second light input face; - at least a first portion comprising a first light input face for receiving first light rays from a first light source and transmitting the first light rays directly toward a light output face so that the light exits the optical part; and - at least a second portion comprising a second light input face for receiving second light rays from a second light source and transmitting the second light rays toward said light output face so that they are reflected at least one time by total internal reflection on a first zone of said light output face before exiting the optical part through a second zone of said light output face, characterized in that the at least one second portion protrudes from the at least one first portion, the optical part comprising a plurality of first portions comprising each a first light input face and a plurality of second portions comprising each a second light input face; - a plurality of first light sources each opposite an associated first light input face of a first portion; - a plurality of second light sources each opposite an associated second light input face of a second portion; and - wherein each first light input face is associated to a first light source and each second light input face is associated to a second light source.
