1. A light-emitting module, comprising:
a light source configured to participate in the performance of at least one photometric function;
an electrochromic device comprising at least one segment arranged downstream of the light source and capable of selectively having a scattering aspect and a transparent aspect;
a controller configured to receive an instruction to emit said photometric function and to control, depending on said instruction, the emission of light by the light source and the appearance of the electrochromic device;
a reflective surface configured to collect and reflect light rays emitted by the light source; and
a projecting lens arranged downstream of the electrochromic device to project a light beam, wherein the projecting lens has a focus located adjacent to an edge of the reflective surface so that the light beam has a horizontal cut-off when the electrochromic device has the transparent aspect.
