Abstract: Plumbing devices (10,30,60) are described comprising a source of light in a gimbal system (12,13,51,72) for providing two oppositely directed aligned vertically oriented beams of light. The gimbal system (12,13,51,72) is removably attached to a support (14,31,61). A handle (14a,45,62) is provided for holding the plumbing device at various distances from underlying and overlying surfaces. Each of the light beams can be focused individually. A windshield (15) is provided for removable attachment to the support for preventing wind induced oscillation of the light source. A rigid frame (32,33,65) is provided for holding the light source in a fixed position relative to an object to be plumbed and for removable attachment to the object while the object is being plumbed.

Abstract: A tubular aluminum housing, having vertically centered pinpoint light bulbs at either end in nose cones, is suspended on a stand by a gimbal system, and has an on-off switch and batteries such that the light bulbs will emit aligned light beams above and below the housing. The nose cones are threaded onto the housing such that they can be moved upwardly and downwardly for focusing of the light beams. Colluminator and magnifying lenses are contained in the nose cones for magnification and additional focusing. A wind shield is disposed on the stand around the housing.
