Abstract

PURPOSE:To allow a rotary warning light on an automobile roof to also send a signal to a vehicle running ahead or behind by controlling activation and blinking of electric lights and rotation and stopping of reflecting mirrors in a response to a selected warning or transmit mode. CONSTITUTION:A rotary warning light has more than one rotatable reflecting mirror and more than one electric lamp supplying light to them, both of which are installed lengthwise in a globe which is long in a direction at right angle to a direction in which an automobile is running and which is capable of transmitting light. Upon selection of transmit mode in lieu of warning mode, a broadcast mode switch-on signal goes to H and is supplied to a switch circuit 30 via a AND gate 29. This causes a switch 30a for a motor 12 to be turned off and a switch 30b for a solenoid 24 to be turned on, which in turns stops the rotation of the reflecting mirrors. As a pin interlocking with the solenoid 24 is inserted into a hole of the rotary light, the reflecting mirrors stop, facing ahead, for example. On the other hand, the electric lamps that have been lit or flashing start blinking in sequence, allowing signal transmission to a vehicle running ahead.
