A bit more old-school than the Park Right Garage Laser, but still just as functional. The Park Right Ball Park helps you park in the right spot every time. The ball park helps you prevent damage to your car and your garage. Simply screw the included eye-hook into the ceiling in the place you wish to park and adjust the string, so the ball touches your windshield. The ball will then light up when it touches your car letting you know you have parked correctly.
