A device and method for validating license plates has a central server in communication with third party databases, external communication means, a fleet of indicators upon license plates of vehicles, and the indicators communicating to the central server. The central server receives input from insurance company, vehicle registration, law enforcement, and subscriber databases. The central server compares a license plate or other data to criteria. Upon meeting one criterion, the central server sends a signal through the communication means to an indicator upon a subscriber's license plate for illumination. Upon failing another criterion, the central server communicates a different signal to an indicator for intermittent illumination. The central server also has an emergency function that a subscriber may activate which illuminates the indicator. The indicator unit has an antenna, a battery, a connection to a vehicle's electrical system, a microprocessor, and a light emitting diode. |
