Abstract: Apparatus, methods, and other embodiments associated with illuminating door handles and door lock mechanisms are described herein. In one embodiment of a door-illuminating device for illuminating a locking mechanism that is secured to a door and illuminating a door handle that is secured to the door, the device includes a housing, a light source, a source of power, a first opening in the housing, and a second opening in the housing. The housing is secured to the door and the light source and power source are secured within the housing, where the power source is in electrical communication with the light source. The first opening may selectively direct light emitted from the light source to the locking mechanism, and a second opening may selectively direct light emitted from the light source to the door handle.
