With your own personal stop sign, you'll know exactly where to stop. No more risking bumping into something and damaging the car. Just put this flexible (won't dent or scratch!) stop sign where you need to stop. When your car's bumper touches the flexible Fiberglass pole, flashing LEDs let you know you're parked in the ideal position. No more damage caused by bumping into obstructions, work benches or tools left out. Stands 51" high so it's easy to see, even when you're backing up. A weighted 12" base helps prevent moves.
