1. A cooling system for a vehicle lighting module with at least two light sources emitting light perpendicular to each other and with one of the light sources emitting light away from the other light source comprising at least one heat sink and at least one axial-circulation member for axially circulating a fluid, the heat sink including a first heat-dissipating surface which extends in a first plane of extension and a second heat-dissipating surface which extends in a second plane of extension secant with the first plane of extension, at least a thermal-dissipation member projecting from the first dissipating surface, at least one wall which, with the axial-circulation member and with the second dissipating surface, at least partially delimits a fluid-circulation chamber for the fluid, which opens via a fluid outlet onto the thermal-dissipation member or members, with the thermal-dissipation member or members extending over and outside of the fluid-circulation chamber towards the at least one axial-circulation member.
