Abstract: A system for enhancing the safety and functionality of a motorcycle or bicycle type helmet includes built-in turn and brake indicators, a transceiver for wireless communications with a corresponding transceiver mounted on a motorcycle, bicycle, or other vehicle, and a speaker and a microphone. The speaker and microphone permits two-way audio communications between the wearer of the helmet and others, either through a cellular network or through a wireless connection to the helmet of a passenger of the vehicle, and further permits such enhanced features as transmission of voice instructions to a navigation system and reception/playback of responsive navigation information, playback from a music system, and audio feedback that the turn signals are being operated, as well as anti-theft protection.
