摘要： An electronic system for driving a lamp of a blinker of a vehicle may include a switch having a first input terminal configured to receive a battery voltage, a second input control terminal configured to receive a control signal for operating the switch, and an output terminal. The system may also include a change-over switch configured to connect, alternatively, the output terminal of the switch to the lamp and to a high impedance reference. The system may also include an electronic device connected to the switch and configured to detect a voltage drop between the first input terminal and the output terminal, and, based upon the voltage drop, generate the control signal to have a value to maintain the switch open for a time interval, and generate the control signal to have a second value to maintain the switch closed for another time interval.
