PURPOSE:To reduce the discharge of battery without flowing dark current even if the state not using a car keeps for a long time, by starting the operation when the switch in the car drive state detection circuit is ON. CONSTITUTION:When a light switch 8 is ON from any ignition switch 6 in a car drive state detection circuit 27, a switch group 28 controlled with a transmitter 18 as a multiplex communication circuit starts operation. Further, one or a plurality of switch groups 28 are ON, allowing to operate one or a plurality of components of the load groups such as a stop lamp 15 from the turn signal 13 of the load group 29 to be controlled corresponding to the switch groups 10-12 with a multiplex communication circuit 40. Further, if a car is not used for a long time, the dark current flowing is prevented and the discharge of the battery 1 is decreased. |
