The Parkez Flashing LED Stop Sign is an excellent addition to any garage. Bumping or scratching a car while parking has happened to most of us, especially in small and tight spaces. The LED lights in the stop sign flash a warning when a vehicle gets too close, allowing the driver to park the car at a safe distance, even on nights when it's hard to see. The stop sign's weighted base keeps it from being easily knocked over and works wonderfully in tight spaces like your garage, but just as well in an outdoor parking area. It's easy to install and helps you detect when your car bumper is getting too close to the stop sign pole with motion-detecting sensors and flashing lights. You can easily adjust the height to suit your vehicle.
