Abstract: A system is provided that enables communications between a driver of a vehicle and a person outside the vehicle, between a rider of a motorcycle and a fellow rider of the same vehicle, or between a driver of a vehicle and another driver of another vehicle. A Bluetooth communication system comprises a Bluetooth communication device mountable to a helmet, and an indicator unit having an indicator disposed in a viewing range of a driver of such a vehicle as a car or a boat. It further comprises a transmitting module disposed in the Bluetooth communication device for transmitting an indication signal to the indicator in response to reception of a calling signal and a receiving module disposed in the indicator unit for driving the indicator in response to reception of the indication signal. The indicator indicates when a call arrives at a Bluetooth communication device mounted on a helmet.

Abstract: A CD changer support device mountable in a trunk forming a luggage compartment of a motorcycle, includes a storage recess to store a CD changer. The storage recess is provided in a luggage compartment-forming wall of the trunk. A swing support device allows the CD changer to swing between a protruding position where the opening of the CD changer protrudes inside the luggage compartment and a storage position where the CD changer is stored within the storage recess. A cover plate covers the CD changer. When the CD changer is in the storage position, the cover plate blocks the opening of the storage recess so as to be flush with the inner surface of the luggage compartment-forming wall. When an operating force is applied to the swing support device, the CD changer swings between the protruding position and the storage position.
