1. An improved module of the type having a light emitting diode and a wafer battery held in a case which improved module provides intermittent light when moved up and down, said module comprising:

  • a case having a floor, two sides and a front comprising a lighted end and an LED supporting cavity at the lighted end thereof;

    an LED held in said LED supporting cavity of said case, said LED having a transparent lens portion, an upper conductor and a lower conductor, said LED being supported in said case so that the lower conductor is adjacent said floor and the upper conductor is supported in a cantilevered manner from said transparent lens portion above said floor;

    a wafer battery having a positive and a negative terminal on a first and second side thereof, said wafer battery being positioned in said case so that one of its positive and negative terminals continuously contacts the lower conductor of said LED and the upper conductor is positioned so that it is spaced from another of the negative and positive terminals of said wafer battery; and

    a weight manner held above the upper conductor of said LED, said weight member being captured by said case and resting on said upper terminal of said LED but said weight manner being permitted some movement so that the weight member moves downwardly by inertia as the module is moved upwardly from a rest position or when a downward movement of the module is stopped, and the downward inertia of the weight member forces the upper conductor of said LED downwardly into contact with the other of the negative and positive terminals of said wafer battery but said weight member and the upper conductor being selected so that the tendency of the upper conductor to bias itself away from the wafer battery will overcome the resting weight of the weight member so that the upper conductor will move away from the wafer battery when the module is at rest, whereby the LED will be lighted by the contact of the upper conductor with the wafer battery when the force of the downward inertia of the weight member overcomes the biased force of the upper conductor which urges the upper conductor away from the wafer battery.
