Fed up with the door and fender dings on your car from pulling into your two-car garage too deep or too far to the side? Then park like a pro, every time, with the Dual Laser-Guided Parking System. Designed specifically for two-car garages, this automatic guidance system allows you to pull into the exact same spot time and time again with laser-beam accuracy! Best of all, the parking system is easy to install, requiring only a Phillips screwdriver. A built-in motion sensor detects when a vehicle approaches, triggering the Laser-Guided Parking System to emit two bright, vertical laser beams from a mounting location on the ceiling. Mount the system using the included screws or double-sided tape, and adjust the individual laser beams to shine on each of the two cars in any location. When you pull in to either space, you"ll know exactly where to stop, because the laser will strike the same spot on your car every time. Features: Avoid hitting the back wall of your garage Let the accuracy of a laser assist your parking Avoid costly repairs to your bumper and/or garage walls Never park "too far" or "too close" in your garage again AC/DC Power or battery powered (9V Battery not included) Includes: Laser base AC Power cord Mounting tape Mounting screws Instructions
