ABSTRACT:
A vehicle horn activation system which is triggered by the forward movement of the vehicle operator's head. An array of light sources and photo detectors create a light curtain which is positioned in a location that allows the driver to move his head into the light curtain, thereby interrupting the emitted light. When the light curtain is broken a signal is generated which activates the horn.
