ABSTRACT:
An automatic fog light cutoff, controlled by the headlights, is described for motor vehicles. The switching circuit for the automatic fog light cutoff is comprised of two current leads connected to each other through a normally-open relay. When the fog lights are switched on, the relay that is connected to the ground of the headlight current lead closes the fog light current lead and thus activates the fog lights. If the headlights are switched on, the current flow in the relay between the fog light current lead and the headlight current lead is interrupted, such that the currentless normally-open relay opens the fog light current lead and shuts off the fog lights.
