Lighting and signalling device of a vehicle

The invention relates to a light emission module of a vehicle, comprising: - a reflector (1) having a focal point, - a primary light source (5) placed at the focal point of the reflector, so as to form a first light beam (F1), - at least one secondary light source (6) placed at a distance from the focal point of the reflector, - a spreading piece (4) capable of being traversed by light and of spreading the rays passing through it, positioned between the secondary light source(s) (6) and the reflector, the reflector (1), the secondary light source(s) (6) and said piece being arranged so that the rays (r1, r2 and r3) emitted by the secondary light source(s) (6) traverse said spreading piece (4) and are then reflected by the reflector, so as to form a second light beam (F2).
