2. Description of the Related Art As a device for guiding a traveling direction by being installed at a construction site or the like, a device formed of a reflector has been generally used. However, this does not serve as a guide except when the vehicle light is illuminated. Therefore, a temporary guide light formed by providing a guide light having an arrow shape on the side surface is used. By installing a plurality of temporary guide lights in a line at a construction site or the like, the direction of travel of a pedestrian or a car can be indicated by arrows of the guide lights.

[0003] Among such temporary guide lights, there are provided temporary guide lights which can be turned on and off to blink. By blinking the guide light, it is possible to draw attention of a person easily. Then, in blinking the guide light in this way, each of the plurality of temporary guide lights arranged side by side is simultaneously turned on.
There are two cases: synchronous flashing for turning off the lights, and scanning flashing for turning on and off the guide lights of a plurality of temporary guide lights arranged side by side. In the latter case of the blinking of the scanning, it is possible to provide visual recognition such that the arrow-shaped guide light moves.

As described above, when a plurality of temporary guide lights are installed at a construction site or the like and each of the temporary guide lights is caused to blink synchronously or to scan and blink, each of the temporary guide lights is provided with a guide light. It is necessary to mutually adjust the timing of turning on and off the lights. Therefore, conventionally, each temporary guide light is connected by a signal line so that the timing of turning on / off the guide light is adjusted.
