<p>PURPOSE: To automatically put out a headlight, a small lamp, and the like in the case of an engine being stopped so as to prevent battery exhaustion by connecting another switch in parallel to a door switch, and turning on this switch on the basis of an engine stop instruction signal from a wireless engine starter. CONSTITUTION: An automatic light driving control device is provided with a light on/out control circuit 3 for judging external light from an optical sensor 1 through a level change detecting circuit 2 so as to light either a headlight 7 or a tail light 8 through a headlight-tail light control circuit 6 and to output according to the opening/closing operation of an automatic light switch 4 and a door switch 5. A switch circuit 17 is connected in parallel between the input and output of the door switch. This switch circuit 17 is switched on by a high level signal supplied simultaneously with the supply of an engine driving stop signal to an engine driving circuit 16 from a code analyzing circuit 15 so as to create a false state of a door opened and to release the operation of the light on/out control circuit 3 and the like.</p> |
