Zusammenfassung:	PROBLEM TO BE SOLVED: To eliminate the need for time correcting work for real time clocks in slave stations and control proper flash control without causing synchronous drift or off-timing. SOLUTION: The assignment of flash control allows is accomplished by feeding a control signal from a control host station 20 to control slave stations 22 (221-22m) using wire or radio communication and feeding it to a timing control timer 32a in a monitor control part 32 via a communication part 34. Electric waves 38 from a GPS satellite 36 are received by a GPS antenna 30a and one-second pulses and time information are fetched by a GPS receiver 30b and fed to the timing control timer 32a. The timing control timer 32a sets a common timer for the slave stations in accordance with the one-second pulses and the time information to generate a flash timing corresponding to the assigned flash control. A light control part 32b is used to perform chain flash control of lamps of approach guidance lights 161. The other control slave stations 222-22m perform similar flash control.
