light controlling system for vehicle, has switching unit whose closed and open states authorize and stop passage of current in power circuits, and control unit conceived to tilt from closed state in opened state and vice versa

摘要

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.
