ABSTRACT:
An automobile electric system including an electrically operated device such as an air conditioning device which is controlled by a control switch and light devices such as head lights which are controlled by a light switch. The control switch is provided with an illuminating lamp which is adapted to indicate the switch positions and the location of the switch. A control circuit for the illuminating lamp is provided so that the lamp illuminates the control switch when the switch is actuated, with a sufficient brightness in day time to show that the switch is actuated, but with a moderate brightness in night time wherein the light switch is actuated. Further, in night time, the control switch is illuminated with a weak light when the control switch is not actuated only to indicate the location of the control switch.
