Abstract
An illuminated level includes a main frame providing parallel spaced-apart flat plane working surfaces connected together by a flat main frame web. The web is provided with three main frame sight ports extending therethrough. A bubble vial is positioned across each of the main frame sight ports. First and second side plates are positioned, one on either side of the web. Mounted on one of these side plates in adjacent relation to the web are six light emitting diodes, each positioned in adjacent relationship to an end portion of one of the three bubbles vials. A switch and a battery are also mounted to this side plate as are appropriate electrical conductors. The electrical conductors couple the light emitting diodes, the battery and the switch to cause energization of the light emitting diodes when the switch is actuated.
