At night, stop lights make it easier for the driver to stop, thereby avoiding collisions. However, these lights consume a lot of energy from your car battery. This is an automatic stop light system with zero standby current. The circuit is designed to automatically detect from the back or front when a vehicle approaches, and turn on the stop light for 30 seconds.
