A lighting module for an automotive vehicle. The module comprises a support, for example made by a heat dissipation device, and a printed circuit board accommodating at least one light source of a first type. The printed circuit board is housed on the support. The lighting module proposes allowing light sources of a second type, generating, for example, a different amount of heat, to be housed so that the rays arising from the two types of sources may be coupled into one and the same light guide, while efficiently dissipating the heat generated by each of the types of light sources.
