1. A vehicle identification system, comprising:

  • a vehicle comprising an electrical power bus which distributes electrical power to various electrical systems in the vehicle;

    optical wavelength carrier communicating means connected to said vehicle for producing an optical identification signal representing an identity of said vehicle, said optical identification signal including an optical wavelength carrier signal, wherein said optical wavelength carrier communicating means comprises;

    identification signal generating means for generating an identification signal representing an identity of said vehicle;

    identity communication means responsive to said identification signal generating means for communicating said identification signal over said power bus, wherein said identity communication means communicates said identification signal using spread spectrum techniques; and

    an optical transmitter, electrically connected to the power bus, for receiving electrical power and the identification signal and for producing an optical identification signal representing the identity of said vehicle from the received identification signal; and

    identity determining means positioned external to said vehicle and responsive to said optical wavelength carrier communicating means for determining an identity of said vehicle from said optical identification signal.
