ABSTRACT:
A door lock illumination apparatus is provided for illuminating a door lock assembly carried by a dwelling door which is adjacent to a dwelling door frame and which is in close proximity to a storm door and to an AC power source. The door lock illumination apparatus includes a storm-door-responsive switch assembly mounted on a portion of the dwelling door frame. An AC-powered illumination source is mounted on a portion of the dwelling door frame in proximity to the door lock assembly. A first conductor assembly is connected between the AC-powered illumination source and the storm-door-responsive switch assembly. A second conductor assembly is connected between the storm-door-responsive switch assembly and the AC power source, and a third conductor assembly is connected between the AC-powered illumination source and the AC power source. The storm-door-responsive switch assembly includes a normally closed switch. A storm-door-contacting switch actuator contacts the storm door when the storm door is closed. The normally closed switch remains open when the storm door is in contact with the storm-door-contacting switch actuator, and the normally closed switch closes when the storm door is removed from contact with the storm-door-contacting switch actuator.
