1. A remote controlled locking system comprising:

  • a transmitter for transmitting locking and unlocking signals;

    a locking mechanism that is locked and unlocked in response to the locking and unlocking signals transmitted by the transmitter, and which outputs first and second output signals corresponding to the locking and unlocking signals;

    control electronics coupled to the locking mechanism for processing the first and second output signals and for providing first and second control signals in response thereto;

    first and second light emitting members that are respectively responsive to the first and second control signals and which respectively provide first and second light output signals in response to the first and second control signals;

    first and second input prism couplers affixed to a surface of a window and that are optically coupled to the first and second light emitting members; and

    first and second hologram decals affixed to the surface of the window that are respectively responsive to the first and second light output signals, that respectively display a visible message indicative of the status of the locking mechanism.
