The Garage Stoplight

This is the color-changing light that helps prevent your car from bumping into the garage. Mounted to a garage's back wall, the light’s integrated ultrasonic distance sensor can be set from 6" up to 6'. As a car pulls into the garage, the light automatically changes color from green to yellow to red when it reaches the preset distance limit. Its six bright LEDs are easily visible with a wide viewing angle and high intensity light, and are rated for 30,000 hours. Includes mounting tape and a hook and loop fastener. Requires four AA batteries that provide power for 5-6 months; sensor flashes red when batteries need replacing. 3 1/2" W x 4 3/4" H.
