Mandark Flashing LED Stop Sign for Garage Parking Assist, Adjustable Height Automotive Garage Parking Stopper, Vehicle Exterior Stop Indicator Sensors, Universal for RV, SUV, Truck

This is definitely a working solution to knowing when to stop your vehicle in the garage. For me, I'm using this in addition to a tire stop and this lets me know when I'm within a couple of inches of the tire stop. The stop sign also helps you line up the vehicle being that garages can be very tight. Once you bump it, it activate the motion lights. And...if it's not needed, (Ex. working in the garage), you can move it out of the way, unlike the hanging tennis ball. But quality wise, the plastic pole is pretty thin so if you trip over it, I'm not sure it will survive. But other than that, it does the job.

This is a decent practical stop sign to help you stop your car in the garage before hitting whatever it is in front of your car (like a wall or stored item). NOTE: I am reviewing based on the bump and spring movement of the stop sign support to tell you to stop the car! which is fine. I did not review the LED light action (yet). Luckily my garage is light enough to see the sign without fancy LED lights that need batteries (included).
