ABSTRACT:
A luminescent door knob cover. The cover is molded from an admixture of a phosphorescent powder and a carrier. A first half of the cover overlies a first half of a door knob and the first half of a door knob neck when the device is operatively installed. A second half of the cover overlies a second half of the door knob and the second half of the door knob neck when the device is operatively installed. A hinge is formed in the cover to facilitate placing it on and removing it from door knobs. An annular band secures the cover to the door knob.
