Abstract
A tubular-shaped spirit vial is provided which is capable of being illuminated at its ends, offering improved observation of the spirit bubble location. The spirit vial has particular application in carpenter's and other tradesperson's levels providing greater ease in making, and more accurate, horizontal and vertical level determinations in poorly lighted work areas and against dark wood.
