Abstract

The system has power circuits (1, 2) whose power supply units provide supply current to power light of a vehicle. A switching unit (K1) includes closed and open states that respectively authorize and stop passage of current in the corresponding power circuits. A single control unit (3) is conceived to tilt from the closed state in an opened state and vice versa. The control unit is designed to deliver a control signal (C1) to the units of the power circuits, where the signal is modulated in width of impulse.
