An automotive reconfigurable interior overhead light assembly comprising: • a support body (2, 13) fastenable in a seat made in an interior roof of a motor vehicle; • a printed circuit carried by the support body (2, 13) and comprising electrically conductive tracks formed to define electrical I/O terminals of the printed circuit engageable by an external electrical connector, electrical terminals to electrically connect at least one electric light source, electrical terminals to electrically connect at least one electrical switch, and an electrical circuit to connect the electrical switch and the electric light source to each other and to the electrical I/O terminals of the printed circuit; • at least one electric light source electrically connected to the corresponding electrical terminals of the printed circuit for lighting an area of the motor vehicle interior; and • at least one electrical switch electrically connected to the corresponding electrical terminals of the printed circuit to control the electric light source; wherein the printed circuit is designed to allow: a) interchangeability of the electric light source, so as to allow indifferent usage of different types of electric light sources that, due to their nature or operating mode, require different circuit topologies for their power supply; and b) interchangeability of the electrical switch so as to allow indifferent usage of different types of electrical switches that, due to their nature or operating mode, require different circuit topologies to switch the electric light source on and off; characterized in that the printed circuit is further designed to allow: c) backlighting of an electrical switch, when an electrical switch fitted with a cover having a backlightable ideogram is used in the overhead light assembly; wherein, as to allow reconfiguration as in c), the printed circuit is designed to form, at each location of an electrical switch that can be chosen as a backlit or non-backlit switch, two power supply terminals connected to the electrical I/O terminals of the printed circuit and to which corresponding electrical terminals of an electric backlight source may be electrically connected. • a support body (2, 13) fastenable in a seat made in an interior roof of a motor vehicle;
