Abstract
A tool incorporating a device that generates a light line on a work surface such as a wall is disclosed. The device includes a housing containing a self-leveling pendulum assembly and a light source that directs a light beam along a pathway. A redirection assembly, also contained in the housing, is capable of altering the pathway of the light beam prior to exiting the housing. In use, the device selectively generates a light line on the work surface in a desired direction.
