1. An inter-vehicle communication apparatus comprising:
- a radio frequency transmitter associated with a first vehicle, the radio frequency transmitter modulates a first audio signal onto a radio frequency signal;
a radio associated with a second vehicle, the radio demodulates the first audio signal from the radio frequency signal and presents the first audio signal for listening within the second vehicle;
a light source mounted on the first vehicle, the light source emits light in a direction towards the second vehicle;
a detector mounted on the first vehicle and positioned to receive at least part of the light that is reflected from the second vehicle, the detector converting the at least part of the light into an electrical signal;
an audio detector operatively coupled to the detector, the audio detector receives the electrical signal and the audio detector extracts a second audio signal from the electrical signal; and
an audio output device, the audio output device receives the second audio signal from the audio detector and reproduces the second audio signal to be audible within the first vehicle.

Abstract
An application for a two-way communication system for communicating with a person who is within a second vehicle includes a short-range radio transmitter within a first vehicle to transmit audio to a radio within the second vehicle. Communication from the person in the second vehicle to a person in the first vehicle is performed by aiming a light beam from the first vehicle at the second vehicle and receiving reflections of the light beam at the first vehicle. The light beam is modulated by vibration of the second vehicle caused by the person speaking in the second vehicle. The received light beam is then processed to reproduce the sound of the person'"'"'s voice.
