INPUT LIGHTING SIGNAL OPTIMIZATION DEVICE AND METHOD

An input lighting signal optimization device includes a multiplex circuit configured to select and output a first LED lamp lighting signal or a second LED lamp lighting signal, and a MICOM configured to output a driving signal for driving a first LED lamp or a second LED lamp after receiving an output signal of the multiplex circuit through one input port and detecting a wake-up signal included in the output signal of the multiplex circuit to switch to an activation mode.
