A lighting device and system having a faceplate and a backplate. The faceplate or the backplate may have an arm or a set of arms having electrical conductors to connect or couple to the electrical contact points of an outlet, plug, or switch. The electrical conductors can receive a voltage from a voltage source such as an AC voltage source. A voltage regulation circuit may provide for the regulation or conversion of the voltage source. A switch can allow for a control circuit connected to the voltage regulation circuit to be bypassed or switch from one operational mode to another operational mode. The operational modes may be in an emergency lighting mode, and a nightlight mode. The voltage source can be connected to a light source or sensor through the control circuit or the switch, and the light source may be activated based on the output of the sensor.
