Abstract: An improved module of the type having a light emitting diode and a wafer battery held in the case. The module has a case having a floor, a lighted end and an LED supporting cavity at the lighted end. An LED is supported in the case so that its lower conductor is adjacent the floor and its upper conductor is supported in a cantilevered manner from the transparent lens portion of the LED. A wafer battery having a positive and a negative terminal on each side thereof, is positioned so that one of its terminals continuously contacts the lower conductor of the LED and the upper conductor is positioned so that it is spaced from the other terminal of the wafer battery. A weight member is held above the upper terminal of the LED and the weight member has sufficient weight so that it will move the upper conductor downwardly when the weight is moving downwardly by inertia but will not have sufficient weight to move the upper conductor into contact with the wafer battery when the module is at rest.
