Abstract
A flashlight has a housing with a recess through which is passed a light beam from a light source to a light receiver. The receiver is coupled through a microprocessor to energize the bulb of the flashlight upon interruption of the light beam by an individual's finger or by a mechanical element movable between positions interrupting and not interrupting the light beam.
