Abstract
The installable headlight alarm system is a device that detects when the headlights of an automobile are on when the engine is not operating, using only the electrical signals present at the automobile's headlight connector. This method of detection allows the system to be easily installed on any automobile, by attaching it to the connectors of the automobile's headlights.
