Abstract
A head lamps control system for use on a vehicle for turning on and off the head lamps of the vehicle according to the brightness of the outside of the vehicle, in which a flip flop circuit is set upon closing of an ignition switch and in this set condition it receives power from a DC power source of the vehicle via a fuse to make on-off control for the head lamps in accordance with a signal provided from a photosensor which detects the outside brightness. To the above fuse is connected a load other than this system, and in the event the above fuse opens due to some trouble of such load, power can be fed to this system from a power supply path via the ignition switch, to prevent the head lamps from suddenly going off.
