This Garage Parking Signal is designed to be run into! When your bumper taps the flexible stand, the bright red LED bulbs flash, letting you know you're positioned perfectly. No more worries about running into the lawnmower, bicycles and garden equipment. In a dangerous situation? - A hazard setting is available to use as an emergency flasher. It's also an especially helpful way to teach teens parking and driving techniques. Easy to install--just add the long-life batteries (included) and set into place!
