Claim:
A laser level assembly comprising: a main body; at least two light emitting device mounting portions arranged substantially opposite each other around the circumference of the main body; a main body mounting for the main body to be rotatably mounted within a housing of the laser level such that the main body may reside on a substantially vertical plane rotatable under the effect of gravity; and at least one moveable weight attached to the main body that may be moved between stable positions to adjust the position of the main body under gravity around its rotatable mounting; wherein at least one of said light emitting device mounting portions is hingedly mounted to the main body and rotatable in the plane of the housing, and wherein said at least one of said light emitting device mounting portions is adjustable to fixed positions in that rotation within the plane of the housing to bring a light emitting device into a substantially co-linear alignment with a light emitting device on an opposed side of said main body.
