ABSTRACT:
An elemental flashlight utilizes a very simple, one-piece molded plastic frame which has open, clip-end mounts for a bulb and battery, with a conductor connecting between the bottom of the battery mount to the band contact of the light bulb so that when the battery is snapped into its mounted position the flashlight is on, and when the battery is inserted upside-down the nipple contact misses the conductor, so that the bulb is not lit.
