摘要:
A level includes a frame having a top planar surface, a bottom planar surface, and a web coupling the top planar surface to the bottom planar surface. The top planar surface and the bottom planar surface are parallel. The level further includes a vial supported by the frame. The vial has a longitudinal axis passing through a center of the vial and a body defining an interior containing a liquid and an indicator bubble. The level further includes a plurality of LEDs. Each of the LEDs has a light emitting point, and each of the plurality of LEDs is positioned adjacent an end of the vial and is oriented such that the light emitting point is positioned within the interior of the body of the vial.
