PURPOSE: To provide a guiding light/emergency light lighting device for which the number of part is reduced to improve assembling by providing a printed circuit board and an inspection switch which intentionally forms the condition of service interruption, and which is formed on the printed circuit board.

CONSTITUTION: A guiding light/emergency light lighting device is formed on a printed circuit board 10 provided with an emergency battery terminal 11 on one end and a power source/ballast terminal 12 on the other end. An inspection switch is placed in the power source/ballast terminal 12, and the lighting device is switched into the lighting of an emergency light by pulling a pull string 25, and the terminal 12 is provided with a monitor lamp 26, an electric wire 27 connected to the ballast, an electric wire 28 connected to a socket, an electric wire inserting hole 29 for feeding, and an electric wire 30 for earthing. The battery terminal 11 is provided with a connector 14 and a fuse 16 connected to the connector 13 of a storage battery which becomes an emergency power source at the time of service interruption and a chord 15 connected to a lamp socket. The wiring is drastically reduced, and a guiding light/ emergency light lighting device of improved assembling performance and workability is thus provided.
