Pyle PLPSE4P 4 Parking Sensor System & LED Display, 2.0-0.3m (6.56-0.98') Display Distance

The Pyle PLPSE4P 4 Parking Sensor System and LED Display is the perfect accessory for parking with a large vehicle or for the frequent parallel parker- any place where parking is tight. It includes 4 sensors, the central "brain" unit and a display. Hooked up altogether, this is a truly ingenious system perfect for letting you know how close you are to obstacles, walls, or other vehicles. The 7-stage LED indicator shows how close you are to objects, from 0.3 to 2.0 m. It can be set up to activate when you put your car in reverse. It requires 12 V from your vehicle's battery.
