Abstract
Described in this application for patent is a novel method and apparatus for modifying a searchlight from a visible-light source to an infrared source. This selective filtering is accomplished by means of a partially filtered cover about the light source which may be moved between first and second positions. In a first position, light projected by the light source passes through an unfiltered section of the lamp cover. In a second position, light projected by the light source passes through a filtered section of the lamp cover.
