A support for one or more light sources for a lighting and/or light-signaling module for an automotive vehicle, comprising a substrate made of heat-conducting material, preferably made of a metal material, at least one light source of light-emitting diode type with one face for mounting on the substrate, in thermal contact with the latter and a circuit for controlling the electrical power supply of the one or more light sources. The circuit for controlling the power supply is electrically connected to the one or more light sources by means of metal wires that are soldered to the surface using the technique commonly referred to as “wire/ribbon bonding”. A method for assembling such a support.
