Abstract: A combined night light and alarm device preferably includes a portable housing, a light emitting section located inside the housing, an alarm section located inside the housing, and a plug attached to the housing and adapted to be removably connected to an existing electrical outlet. An audible alarm is included for notifying residents/occupants when the device senses motion of unauthorized persons. Such a plug may be electrically coupled to the light emitting section and the alarm section respectively. A logic gate may be located inside the housing. Such a logic gate may be electrically coupled to the light emitting section and the alarm section respectively. In this manner, the logic gate cooperates with the light emitting section and the alarm section in such a manner that light and sound are automatically emitted upon simultaneously detecting first and second triggering events around the housing.
