This invention relates to an electronic anti-theft device for a motor vehicl e. The device simulates the operation of a security alarm system. To give the appearance that a motor vehicle is equipped with a security alar m system, it is common to use a light-emitting diode, or a similar light-emitting mechanism, ("LED"), installed, possibly with the aid of an LED holder, at the vehicle's steering wheel column, dashboard,.floor console or another highly visible location. The LED is powered by the vehicle's battery and, while activated, flashes on and off to deter thieves. The LED remains activated or a switch is incorporated for manual activation and deactivation . Alternatively, by splicing into the vehicle's ignition wires, the LED is automatically, activated while the vehicle's ignition system is off and, deactivated while the ignition system is on. The present invention comprises an improved means of installing the LED such that it is automatically, activated while the motor vehicle's ignition system is off an d, deactivated while the ignition system is on, without having to splice into the vehicle's ignition wires. Furthermore, the invention incorporates either a fuse or a circuit breaker to guard again st a circuit overload and means by which to adjust the characteristics of the LED's flash. Finally , the invention is compatible with the actual LED, and any related assembly thereto, that forms part of the security alarm system supplied by the vehicle's manufacturer.
