Improve parking safety and reduce the risk of collisions with the iBeam TE-B4PSK 4-Sensor Rear Parking Assist Kit, designed for use on cars, trucks, SUVs, vans, RVs, and commercial vehicles equipped with compatible rear bumpers. This ultrasonic parking system helps drivers detect obstacles behind the vehicle during reversing and low-speed maneuvering. The system uses 4 ultrasonic rear sensors mounted in the bumper to detect objects within a range of up to 5 feet (rear detection zone). As distance decreases, the system provides an audible warning through an adjustable buzzer, increasing in frequency to help the driver better judge proximity to obstacles. The TE-B4PSK includes a control module and ultrasonic sensor system, designed for integration into standard 12V vehicle electrical systems (9–16V operating range). The system activates automatically when the vehicle is placed into reverse when wired to the reverse light circuit. The sensor heads are designed for bumper installation, and installation requires drilling mounting holes using the included hardware. The system is intended for use on non-metal bumpers (plastic bumpers recommended per manufacturer guidance) for proper ultrasonic performance. The kit includes four ultrasonic sensors, control module, wiring harness, and audible alert buzzer, providing a complete rear parking assist solution for improved driver awareness. The iBeam TE-B4PSK is a practical driver assistance system designed to enhance rear visibility awareness and help reduce reversing accidents in everyday and commercial driving environments.
