Safety eyes are mounted on the bottom of the track near the opening. If the garage door is closing and there is a person, pet, or object beneath the door in the garage opening, the safety eyes send a signal to the opener to reverse and return to the open position to avoid injury.

If your garage door doesn’t have safety eyes, and you’re wondering if you can add them to your existing opener, in short, the answer is “it depends.” But read on to determine what your course of action should take to ensure your garage door has safety eyes.

Your garage door opener was manufactured AFTER 1993: Your garage door was sold with safety eyes. If they broke or are lost, you can replace the safety eyes without replacing your garage door opener.

Properly installed safety eyes should be mounted on the bottom of the track 3-6” off the ground. This helps ensure that no person, pet, or object can sneak beneath the sensor and possibly get injured from the closing door. They should be bolted to the track, not just clipped on so they can’t be easily knocked out of position. The wires should be pigtailed to eliminate the chance of them getting pulled from activity in the garage. You can test your garage door safety eyes by checking for a LED light on each sensor.
