⚡ At a Glance
- • Detection Range: Audio alerts begin from just over 1 metre and become continuous at 30 centimetres
- • Best for: Drivers who want discreet, colour-matched reversing assistance and simple DIY fitting
- • Not ideal for: Users who prefer a visual display or camera-based reversing system
Four ultrasonic sensors provide progressive proximity detection from about 1 m down to 30 cm. Factory-baked colour options and a waterproof swap socket simplify fitting and future replacement.
Confident parking in tight spaces - with four ultrasonic sensors and progressive audio alerts
Ultrasonic radar sensors monitor the area behind the vehicle and send signals to the brain box, which translates distance into an audible pattern from slow beeps to a continuous tone at around 30 cm. Sensors sit on 2.5 m cables connected to a central control unit and buzzer.
Progressive beeping helps judge closing distance accurately when reversing, reducing minor bumps and scrapes in confined spaces. The buzzer on a 2 m lead gives clear cabin warning without needing a separate display.
Neat, colour-matched finish - thanks to 32 factory-baked paint options
Sensors are finished in a choice of 32 colours with the paint baked on at the factory rather than sprayed afterwards, giving a more durable coating. An alternative matt black option is supplied for anyone planning to paint parts themselves.
A close colour match keeps the bumper looking original and discreet once installed, avoiding obvious aftermarket patches. Factory finish also resists weathering better than retro-sprayed alternatives.
Easy DIY install and low-effort maintenance - with supplied cutter, waterproof sockets and adjustable sensitivity
The kit includes a 21 mm hole cutter and sensors that fit a 21 mm hole with a 25 mm outer face to leave a 2 mm overlap for a tidy finish. A waterproof swap socket sits about 6 inches from each sensor head and the brain box features an adjustable sensitivity control; extension leads and a display upgrade are available.
Most competent DIYers can fit the kit using the supplied tools and wiring to the reversing light, enabling automatic activation when reverse gear is selected. Quick-swap sockets reduce the need for cutting or soldering when replacing sensors or extending runs for larger vehicles.
