Abstract
A voltage detecting means, such as a voltage winding, a zener diode or the like, is connected across a power source and is operative when the voltage applied thereto exceeds a predetermined value owing to a disconnection of a main lamp also connected across said power source. A disconnection indicating means, such as a lamp, is connected to the voltage detecting means and is energized when the volage detecting means operates.
