The present invention is directed to vehicle communication equipment
capable of transferring information using light without adding new light
emitting means, and further, between a stationary apparatus and a vehicle
or between vehicles. A light emitted from a signal lamp (11) of a
stationarily installed traffic signal (10) or a head lamp (35) or a tail
lamp (36) of a vehicle (20) is superimposed with a signal by a modulator
(13), the modulated light is received by a light receiving unit (21) of
the vehicle (20) side, and the received modulated light is demodulated by
a decoder (22) to be displayed on a display panel (24).
