Abstract

A wand light has a base tube (1) with a light-tube end in which a base end of a light tube (9) is pivotal concentrically with pivotal-light-switch attachment of the light tube to the base tube. The base tube contains a stored-energy unit (2) in addition to being a handle and a daytime signaler. The light tube contains a light emitter which can include a flashlight bulb (35) or a plurality of light-emitting diode units (18) on a circuit board (14). The light tube is twisted in the base tube for selective switching of current for the light emitter. Moisture-proof pivotal attachment of the light tube to the base tube, moisture-proof construction of the light tube and moisture-proof construction of the base tube render the entire wand light moisture-proof. Predetermined ruggedness, diameter, length, diameter per length and length of the light tube per length of the base tube render it adaptable to a wide variety of uses. Accidental and unintentional switching are prevented with twist switching. Daytime signaling is provided by appropriate coloring and brightness of coloring of the base tube while being handheld with the light tube. Nighttime signaling is provided by appropriate coloring and brightness of coloring of the light tube and the light emitters while being handheld with the base tube.
