The indicating device is adapted to be installed on a platform on a headlamp frame with a slip fit and, once installed, is automatically locked into place. The indicating device includes a bubble level having a vial which is molded integrally with a base adapted to be assembled with a spring metal retaining bracket with a slip fit. The retaining bracket includes cantilevered legs with free end portions which resiliently engage the upper side of the base to enable an adjusting screw to tilt the vial upwardly and downwardly to various positions relative to horizontal.
