Reverse Sensor

Parking sensors warn you of obstacles you can't see, with beeps that speed up as you get closer. This range is led by Promata, with 4-sensor front and rear parking assist kits with a buzzer or visual display, and the PSW-81 and PSW-82 wireless kits, the latter designed for trucks and trailers on 12 to 24V.

The Steelmate PTS411M7 works front or rear with voice warnings, and the PTS-V404 combines rear sensors with a 3" monitor and camera. Gator wired and wireless kits are also listed. Sensors are usually drilled into the bumper, so check the colour, mounting angle and cable length for your vehicle.
