Abstract
A lighting device for an automotive vehicle comprising means for controlling the supply of power to a plurality of light sources, the plurality of sources being divided into at least two groups of sources. The device according to the invention is remarkable in that each of the light source groups fulfills a specific lighting function of the device and is distinguished by a requirement for electric current of a specific intensity. Additionally, the control means are capable of selectively supplying power to each of the light source groups exclusively of the other groups. A power supply method implementing the device according to the invention is also proposed.
