Abstract: A system for supplying electrical power to at least one semiconductor-element-including light source of a motor vehicle. The system includes a mechanism controlling the supply of electrical power to the light source and being configured to deliver an electrical current to the light source. Magnitude of the delivered electrical current depends on a bin value of the light source and on the temperature of the environment of the source. An electronic circuit, which is independent of the light source, including a first component a measurable property of which is representative of the bin value of the source, and a second component a measurable property of which is dependent on the temperature of the environment of the light source. The controller determines the properties of the first and second components via a single electrically conductive wire connecting the controller to the electronic circuit, the wire being suitable for supplying the latter with electrical current.
