Abstract
Devices for protecting the bulb of a night light against damage and for denying access to the sockets of an electrical outlet into which the night light is plugged and for also denying access to those parts of the night light which might produce an electrical shock if touched. One component of the protective arrangement is a cover with externally threaded bosses which are apertured so that the night light can be plugged into a socket which a boss overlies by installing the night light through the aperture. The night light includes a bulb surrounding protective shield which is clamped against the boss by a safety cap of the push-and-twist type, thereby protecting the bulb and isolating the socket and electrically charged parts of the night light. Safety caps are also used to deny access to any othe sockets of the outlet servicing the night light, and these safety caps may be designed so that they will perform this function when the protected socket is in use as well as when it is out of service.
