The Detail
No More Guessing at the Wall
01
📡 Ultrasonic Precision, 6 in to 6 ft
The small sensor head reads distance in real time from about 6 inches to 6 feet. No eyeballing, no counting wall tiles — the sensor does the math for you.
02
🚦 Big STOP Sign, Visible Day or Night
A 3.5-inch octagonal STOP sign glows from the driver's seat. Daylight or dark garage, the color change is impossible to miss.
03
🎯 Set Your Own Stop Distance
Pull in once, press the 'Set Distance' button, and the unit remembers your preferred stopping point. Perfect for SUVs, trucks, or low sports cars.
04
🔌 Two Ways to Power It
Plug it in with the included AC adapter for permanent install, or run it on 3× AAA batteries (not included) where there's no outlet. Your call.
05
🛠️ Mounts in Minutes — Tape or Screws
Stick it to the wall with the double-sided tape, or screw it in for a permanent mount. Works on walls, workbenches, shelves — any flat surface facing the car.

How is this different from a tennis ball on a string?
A tennis ball only tells you one fixed point. This sensor reads distance continuously and shows you red, yellow, or green — so you see how close you are before you get there.
Does it work with SUVs and trucks?
Yes. Because you set your own stop distance with the Set Distance button, it works for compact cars, lifted trucks, and low sports cars alike.
Do I need an outlet near the garage wall?
Not necessarily. Plug in the included AC adapter for permanent use, or run it on 3× AAA batteries if there's no outlet nearby.
Is it hard to install?
No. Use the included double-sided tape for a tool-free install, or the screws and wall anchors for a permanent mount. Works on walls, workbenches, or shelves.
Will the light be visible at night?
Yes — the red, yellow, and green LEDs are bright enough to see clearly in a dark garage from the driver's seat.

'My garage is tight and I was always nervous about hitting the wall. Now the red light tells me exactly when to stop. Installed with tape in two minutes.'

'Wasted so much space pulling in too far or too short. Set my distance once and now I park the SUV in the exact same spot every single night.'

Verified Buyer · Replaced Tennis Ball
'Finally threw away the tennis ball on a string. The color progression is way more helpful — I see yellow when I'm close, red when I'm done.'
Lisa Martinez ★★★★★
Verified Buyer · Two-Car Garage
