An assembly mounted in a toy containing a light emitting diode and a battery. The light emitting diode lights when the module is moved. The assembly may be mounted in a toy such as a toy truck with rough tires and the vibration caused by rolling the truck on a flat surface causes the light emitting diode to go on and off. The diode is energized by a movable weight positioned above a wafer battery in the assembly.
