This Pyle Watch Dog series parking sensor system uses 2 sensors to make sure your car is parked in a safe position. The 4 piece rear parking system (2 sensors, brain, display) has a four stage built-in beeping alarm to notify you when you’re getting too close. But best of all, it has a digital distance object indicator with four-color, seven-stage LED display to show you the exact distance you are from the nearest wall. The reverse sensor trigger activates the system so you can back up without worry. Includes sensor cutout tool. Requires 12 V DC.
