Abstract: A method for a driver device of an automotive lighting device that includes at least two inputs for receiving one electricity supply each, and a power converter circuit for selectively converting the electricity supplied on one of the inputs into a periodic power supply for powering said lighting device. The method allows for switching between inputs of the driver device while reducing the power supply shortage which generally arises at the time of switching inputs. This allows for providing generally flicker-free luminosity while using a single converter circuit.
