Ultrasonic Side Mirror Sensor

The Ultrasonic Side Mirror Sensor safely guides your car into and out of the garage. Cordless and easy to install, it illuminates green to indicate it is clear to enter. A bright yellow light indicates when your side view mirror is getting close to the garage opening. A bright red light and siren indicate you are too far over and in danger of damaging your vehicle. Features adjustable settings (4 to 24 from wall) for a perfect park every time.
