Disclosed herein is a device, methods, and systems for a specialized circuit and alert system for use with any motorized vehicle with an integrated electrical system. The circuit may connect to the vehicle electrical system through any available port. When the voltage in the electrical system is high the signal is deactivated, as is the case when the vehicle motor is running and charging the battery and electrical system. When it is low the signal is actuated. The system is further controlled by a switch connected to a sensor or other detection means, which activates the system based upon the presence or absence of an item. The whole of the system therefore operates to activate the system when an item is present and the engine is running, an alert signal is triggered when the vehicle engine is turned off. In the preferred embodiment a sensor is incorporated into a baby seat, and the circuit plugs into the cigarette lighter port.
