Wireless emergency safety light with sensing means for conventional light switch or plug receptacle

A housing for an emergency light source which is mechanically connectable to an electrical switch having a switch actuator or a plug receptacle for providing power to a light fixture or other electrical load, comprising:

• a) a replacement housing for replacement of a conventional switch plate having at least one opening for receiving said switch actuator of said electrical switch or for receiving said electrical plug receptacle;
• means for mechanically connecting said replacement housing to said electrical switch or said plug receptacle;
• said replacement housing having no electrical connection to said conventional switch plate or to said plug receptacle;
• b) at least one compartment in said replacement housing for receiving batteries;
• c) a second compartment in said replacement housing for receiving an emergency light source adapted to be connected to said batteries;
• d) wireless means for sensing the loss of electrical power to said electrical switch or said plug receptacle and, in response thereto, for actuating said emergency light source;
• and
• e) a night light mounted in said replacement housing.
