Abstract
The indicating device includes a bubble level formed by a transparent plastic vial filled with liquid having a gas bubble therein, the bubble coacting with an underlying scale to indicate the degree of tilt of the vial from horizontal. To enhance the visibility of the bubble and enable more accurate readings, portions of the vial are darkened with a strip of black material adapted to be secured to the vial by pressure-sensitive adhesive. A cap for closing the vial is darkened by molding the cap from black-tinted plastic.
