Claim 0:
1. A lighting system for a motor vehicle comprising:
at least one primary optical emission device for emitting a light beam exhibiting a cutoff profile, the at least one primary optical emission device includes at least one light source and one single-piece primary optical member, the primary optical member includes an input surface configured to receive a light beam emitted by said at least one light source, and an output surface through which all rays of the light beam emitted by the at least one light source travel; and
a projection device arranged downstream of and spaced apart from the output surface of the at least one primary optical emission device, the projection device includes an input surface arranged facing the at least one primary optical emission device, and through which are introduced all of the rays of the light beam output from the output surface of the at least one primary optical emission device,
wherein an outer surface of the primary optical member includes a hallowed zone forming a relief in cavity form, a longitudinal axis of a peak of the cavity extends transverse to an optical axis X direction of said lighting system, and
wherein the peak of the cavity is a focal point and forms a ray interception surface for all rays of the light beam emitted by the at least one light source so as to create the cutoff profile in the light beam.
