A communication system is provided with a group registration function, which is capable of setting a group mode with the reduced number of operation, and simply selecting one of full duplex communication and half duplex communication by a rider, as needed. When a power supply switch and a registration switch are turned on simultaneously, member ID registration is executed. When the power supply switch is turned on and then the registration switch is turned on, visitor ID registration is executed. Accordingly, the registration of a group mode can be simplified. After the registration is ended, at the time of turn-off of a visitor conversation switch, full duplex communication is performed among communication devices subjected to member ID registration, and at the time of turn-on of the visitor conversation switch, half duplex communication is performed between the master and all of the slaves.

A moving body detection system for detecting moving bodies by transmitting and receiving signals between the moving bodies. Each moving body transmits an ID code capable of identifying the moving body itself. A detection side moving body receives the ID code signal based on changes in driving conditions, discriminates the received ID signal, and transmits a detection signal with the ID code and the ID code of the detection side moving body itself added thereto. A non-detection side moving body receives the detection signal, and transmits a response signal with its own ID code and the ID code of the detection side moving body added if the ID code added to the detection signal is the same as its own ID code. Furthermore, the detection side moving body receives the response signal and measures the distance to the non-detection side moving body having the same ID code as the response signal.

A headlamp cleaner for a motorcycle includes a frame enclosing a headlamp lens. A cleaning nozzle is attached to an upper half of the frame. The nozzle ejects a cleaning agent downwardly over the lens against wind blowing upward during running of the motorcycle. Therefore, it is possible to minimize an amount of the cleaning agent scattered by the wind. Further, vehicle state detecting units are connected to a controller for the headlamp cleaner. No cleaning agent will be ejected, when the vehicle is detected to be in a condition, or state, where the cleaning agent is likely to disperse. The controller, in combination with the downwardly directed nozzle, is thus unlikely to disperse cleaning fluid toward a windscreen or rider of the motorcycle.
