Abstract
In a load control device of the present invention, an operation signal provided by any one of a group of input switches in an operation input section is converted into a serial signal by a signal transmitting section, and the serial signal is applied through a serial signal line to a signal receiving section. In response to the serial signal, the signal receiving section outputs a response signal for driving a load, or a headlamp or a running light. When no response signal is provided, a NAND circuit applies a signal to an automatic lamp control section to automatically control the lighting of the lamp. That is, when the signal transmitting and receiving system becomes out of order, the lighting of the lamps is automatically controlled, which eliminates difficulties encountered when a vehicle is run during night.
