Illuminating spirit level apparatus

Abstract

An illuminating spirit level apparatus comprises a spirit level base having a first vial assembly, a second vial assembly, a light, and a battery. The vial assemblies are each filled with a fluid, having a metal ball slidably disposed therein and having a pair of electrodes disposed at the central lengthwise point of on each side of the vial. The battery provides an electrical power source for the light, and the battery, the light, the electrodes of the first vial assembly, and the electrodes of the second vial assembly are electrically connected in series through circuitry wiring. When the spirit level base is placed in a level and/or plumb orientation, the metal ball in the relevant vial assembly moves to the center of that vial assembly contacting and electrically connecting the electrodes on either side of the vial assembly, resulting in the light illuminating with electricity from the battery.
