Abstract:
A longitudinally-elongated, hand-held level includes a body having a reference surface, a longitudinally-extending corner adjacent the reference surface, and a plurality of bubble vials for indicating an orientation of the reference surface. One or more battery-powered lights (e.g., LEDs) create a longitudinally elongated light emitting region along the corner to illuminate a longitudinally-elongated area that is adjacent to the level for use in low-light environments. The light(s) may project light through a light guide and/or light diffuser(s) extending along the corner to disperse light along the longitudinal extent of the level. The light(s) may also illuminate the corner(s) of the level and/or the bubble vials to enhance use in low-light environments.
