The invention proposes a light module for a motor vehicle, comprising a first electrical assembly on a first carrier, which harbours a plurality of branches that are connected in parallel, each branch comprising light sources, preferably light-emitting diodes. The module comprises a second carrier which comprises a control unit for controlling the supply of electrical power to the light sources, the control unit including a feedback loop from a reference branch. The invention allows the number of connections between the two carriers of the assembly to be decreased and reliability thereof to be increased.
