4-Sensor 22 mm Parking Sensor with Backlit LED Display

22 mm Backing Radar with Backlit Display: Distance Displayed to the Nearest Centimeter

A car reversing radar is only noticed the day it saves you from hitting a bollard invisible from the driver's seat. This kit combines four 22 mm ultrasonic sensors and a backlit display that shows the distance in digits while modulating the audible alert. You reverse into a tight space, the beeping quickens, the number drops, and you know exactly when to stop. That is all you can ask of a proper 4-sensor reversing radar kit: to turn a stressful maneuver into an automatic action.

The Backlit Display of This Kit, Readable in Bright Sunlight or Underground

Many entry-level kits come with nothing more than a buzzer: you hear it, but you have to guess. Here, the display sits on the dashboard or sticks to the top of the window, and the backlight keeps the digits clear in both low-angled sunlight and the dimness of an underground car park. That is what sets a reversing radar with an LED display apart from a simple warning device: the display replaces guesswork, and you no longer have to look over your shoulder hoping you'll make it.

Six Sensor Colors to Blend into the Bumper

The kit is available in black, white, gray, silver, gold, and blue. The idea is simple and makes all the visual difference: choose the color closest to your bumper so that the 22 mm parking sensors blend into the bodywork instead of standing out. On a light-colored car, a black sensor is visible from ten meters away; a color-matched sensor goes completely unnoticed.

40 kHz Ultrasound and PCB Housing: The Kit's Internal Mechanics

Each probe transmits at 40 kHz with a stated tolerance of 1 kHz and covers a detection range of 0.2 to 2.5 m. The control box, equipped with its own printed circuit board, queries the four channels alternately and eliminates parasitic echoes reflected from the ground. The audible alarm is rated at a minimum of 80 dB, which remains audible with the car radio on. The system operates as a 12V reversing radar, with a tolerated power supply range of 9 to 16 VDC and a current draw of 20 to 200 mA. The stated operating temperature range is -30 to 70 °C: both early morning frost and the heat of a south-facing bumper are covered.

• Four-Point Parking Aid — the entire width of the bumper is covered, including the corners
• Real-Time Distance Display — the display remains continuous from 2.5 m down to 0.2 m
• Graduated Audible Alarm — the beeping quickens as the obstacle approaches
• Six Probe Colors — to match the parking sensor heads to the vehicle's color
• Hole Saw Included — the correct drilling diameter is in the box, with nothing else to buy
• Wide Temperature Range — from -30 to 70 °C according to the manufacturer

Drilling and Wiring This Radar into Your Car's Bumper

Mark four equidistant points across the width of the bumper, at a constant height, between fifty and seventy centimeters from the ground. Drill with the included hole saw, insert the probes, route the wires to the box placed in the trunk, and then take the power from the reversing light — the system will thus only activate when you engage reverse gear. All that remains is to run the display cable up to the dashboard. This reversing radar installation takes one morning if you take your time. One non-negotiable prerequisite: the bumper must be made of plastic, as ultrasonic detection is not reliable through metal reinforcement — check this before installation.

Should You Choose a Radar with a Display or a Parking Camera?

They do not tell you the same thing. A camera shows an image, but flattens distances and cannot see what is below the lens's field of view — a low bollard, a compact car bumper. The radar, on the other hand, gives you a number and a rhythm, even in complete darkness and driving rain when a lens becomes blurred. A reliable reversing radar therefore complements a camera far more than it replaces it. If you have to choose, start with the radar: it is what prevents low-speed collisions.

The Maneuvering Aid Selected by Becquet Voiture

We apply the same standards to detection equipment as we do to our styling parts: sensor molding quality, locked connectors, actual wiring harness lengths, and display readability. Our product sheets provide useful dimensions rather than superlatives, and our French-speaking team is happy to help you choose a color or with the reversing radar installation.

Choose the color of your sensors and make every parking space a formality: order your 22 mm reversing radar.
