A lighting device of an automotive light comprising light sources supplied by a drive current and a control device comprising a control stage generating a control signal on the basis of the difference between the drive current and a predetermined reference current, and a driving stage, which adjust the drive current on the basis of the control signal. The driving stage comprises a voltage stabilizing device, which supplies, in a first operation condition, a stabilized voltage on an intermediate node thereof, a first transistor having a control terminal receiving the control signal; and a second transistor having a control terminal connected to the intermediate node to be set, in the first operation condition, to the predetermined stabilized voltage), a first terminal connected to the light source, and a second terminal connected to a second terminal of the first transistor.
