FirstSafe 4-Sensor LED Parking Sensor Kit – Reverse Radar, 13-Color Display | Universal 12V

FirstSafe 4-Sensor LED Parking Sensor Kit — See Every Obstacle. Stop Every Scrape.

QUICK ANSWER

The FirstSafe KZ-068 is a 4-sensor ultrasonic parking kit with a 13-colour LED distance display and audible alarm. It detects obstacles from 0.3 to 2.5 metres and triggers an alarm from 0.3 to 1.5 metres — automatically activating when reverse is engaged. Compatible with all 12V vehicles. Universal fit, CE and RoHS certified.

The Real Cost of Parking Without Sensors

The average car park scrape in Australia costs between $400 and $1,200 to repair. Rear bumper damage from low obstacles, bollards, concrete barriers, shopping trolleys, and low walls accounts for the majority of minor collision claims made by Australian drivers each year.

These are not high-speed incidents. They happen at 5 km/h in car parks, driveways, and parallel parking situations, the exact speed range where your mirrors show you almost everything but never quite enough.

The FirstSafe 4-Sensor LED Parking Kit costs a fraction of a single bumper repair. It installs in under 2 hours. And from the moment it's installed, it tells you exactly how far you are from every obstacle behind your vehicle in real time, in centimeters, with a color-coded display and an audible alarm that intensifies as you approach.

One parking incident prevented paying for this kit many times over.

Who This Product Is For

This parking sensor kit is designed for:

• Drivers who regularly park in tight urban spaces — CBD car parks, narrow driveways, parallel parking
• SUV, 4WD, and ute owners where rear visibility is limited by vehicle height and length
• New or returning drivers building confidence with reverse parking
• Anyone who has previously damaged a bumper parking and wants to prevent a repeat
• Fleet operators adding safety equipment to work vehicles
• Anyone adding a second layer of safety alongside an existing reversing camera

This product is not designed for:
Vehicles already factory-equipped with OEM parking sensors, or drivers seeking a front-and-rear sensor system. This kit covers the rear bumper only.

What Changes the Moment This Is Installed

Before installation:
You reverse using mirrors, occasional glances over your shoulder, and estimation. Low obstacles — bollards, concrete wheel stops, raised garden edges, shopping trolleys — are invisible in mirrors until you're already in contact with them.

After installation:
The moment you engage reverse, four ultrasonic sensors begin scanning the area behind your vehicle. The 13-colour LED display activates on your dashboard — showing real-time distance in a colour that shifts from green (safe) through yellow (caution) to red (stop). The audible alarm begins at 1.5 metres and intensifies to a continuous tone as you approach 0.3 metres.

You stop when you should stop. Not when you feel the impact.

How It Works — The Technology Explained Simply

Ultrasonic Sensing
Each of the four 22mm sensors emits high-frequency ultrasonic pulses and measures the time taken for those pulses to return after bouncing off an obstacle. This calculation happens continuously — updating your distance reading in real time as you move.

Detection range: 0.3 to 2.5 metres
Alarm activation: 0.3 to 1.5 metres

13-Colour LED Display
The backlit LED display uses colour progression to communicate distance intuitively — no numbers to read, no interpretation required. Green means clear. Yellow means slow. Red means stop. The colour shifts happen progressively as you close the gap, giving you a continuous visual reference rather than a binary on/off warning.

Display cable length: approximately 5 metres — sufficient to route cleanly from rear bumper to dashboard in any standard passenger vehicle.

Automatic Activation
The system activates automatically when reverse gear is engaged and deactivates when you shift out of reverse. No buttons. No manual switching. No possibility of forgetting to turn it on.

Built Different

Sensor Coverage — What Gets Detected

The four sensors are spaced across the rear bumper to provide full-width coverage of the zone behind your vehicle. This configuration detects:

• Concrete parking bollards and wheel stops
• Shopping trolleys and portable obstacles
• Low walls and raised garden edges
• Other vehicles in adjacent parking bays
• Pedestrians and cyclists in reversing path
• Bin enclosures and street furniture

What ultrasonic sensors do not reliably detect:
Very thin objects (metal poles under 5cm diameter), angled surfaces that deflect ultrasonic pulses away from the sensor, and objects above or significantly to the side of the sensor array. For these scenarios, a reversing camera provides complementary coverage — the sensors and camera work together more effectively than either does alone.

Installation Guide — What's Involved

Tools required: Drill with 22mm hole saw bit, wire fish tool or coat hanger for cable routing, electrical tape or heat shrink, basic hand tools.

Installation time: 1.5 to 2.5 hours for a standard passenger vehicle. First-time installers should allow 3 hours.

Step-by-Step Overview:

Step 1 — Plan sensor placement
Mark four equally-spaced positions across the rear bumper — avoiding tow bar receivers, exhaust outlets, and number plate lights. Standard spacing: sensors positioned approximately 45cm apart across a standard bumper width.

Step 2 — Drill sensor holes
Using a 22mm hole saw bit, drill four holes at marked positions. Clean edges with a file to prevent cable abrasion.

Step 3 — Install sensors
Push each sensor through its hole from outside the bumper. Connect sensor cables to the control box — colour-coded for correct positioning.

Step 4 — Route display cable
Route the 5-metre display cable from the control box through the vehicle's interior to the chosen dashboard mounting position. Cable can be routed along door sills and beneath trim panels for a clean finish.

Step 5 — Connect to power
Connect the system's positive lead to the reverse light wire — the system activates automatically when reverse is engaged. Connect negative to chassis ground.

Step 6 — Mount display
Attach the LED display unit to a clear dashboard position visible from the driver's seat. Test by engaging reverse and verifying display activates and sensors respond to obstacles.

⚠️ Professional installation option: If you prefer not to drill your bumper yourself, any auto electrician or car audio installer can complete this installation. Standard installation time quoted by professionals is 1–1.5 hours.

Frequently Asked Questions

Will this work with my car?
Yes. The FirstSafe KZ-068 connects to your vehicle's reverse light circuit and 12V electrical system — compatible with all petrol, diesel, and hybrid vehicles with a 12V system. The 22mm sensor diameter is the most common standard size and fits any bumper with sufficient depth behind the outer surface for sensor mounting.

Can I install this myself?
Yes — with basic DIY confidence and a drill with a 22mm hole saw bit. The installation requires drilling four holes in your rear bumper and routing cables to the dashboard. If you have previously done basic automotive electrical work, this is a straightforward install. If you are not comfortable drilling into your bumper, any auto electrician can complete it for you.

Will drilling affect my car's warranty?
Adding aftermarket accessories can potentially affect factory warranty coverage for the specific area modified. In most cases, a parking sensor installation does not affect powertrain or mechanical warranties. If your vehicle is under factory warranty, check with your dealer before drilling.

How many sensors does this kit include?
Four rear sensors. This kit covers rear parking only. For front coverage, a separate front sensor kit would be required.

What happens if a sensor gets damaged?
Individual sensors are replaceable. Contact hello@veltrixaauto.com with your kit details for replacement sensor availability.

Is the LED display visible in bright Australian sunlight?
The 13-colour backlit LED display is designed for clear visibility in varied lighting conditions. In direct bright sunlight, position the display away from direct glare for best readability — a position angled slightly toward the driver typically works well.

Does it work at night?
Yes. The ultrasonic sensors function in complete darkness — sensing is not dependent on light. The LED display is backlit and clearly visible at night.

What is the RoHS certification?
RoHS (Restriction of Hazardous Substances) certification confirms the product contains no hazardous materials — including lead, mercury, cadmium, and other restricted substances. This certification is required for legal sale in the EU and is a marker of quality material compliance.
