Technological progress is a process of trial and error. Just as cars were once made without seat belts and airplanes didn’t always have windows, garage door openers for sale in 2015 now commonly include safety features and technology that at one time were not standard. It’s unpleasant to think about, but in the early days of mechanized garage doors (mechanized garage door openers became mainstream in the 1950s) accidents and injuries, especially those involving children, were far too common. In order to reverse that trend, the industry responded by standardizing certain features that would make garage door openers safer for public consumption.
One of these features is the inclusion of exterior lights when the garage door opener is installed. These are solar powered and motion activated lights mounted outside your garage door. When you’re inside, these lights can alert you to someone or something lurking around your garage door; they also make it a lot less creepy to arrive home in the dark late at night, particularly if your house stands alone at the end of a long driveway shaded by trees that block out the light from the yellow harvest moon.
Garage door openers also now come standard with safety sensors that prevent the garage door from closing if they sense an obstruction. These safety sensors function like the watchful eyes of a parent, preventing pets, the elderly, careless children, and their bicycles from being crushed by a closing door with no technology to stop it. Any object that triggers the sensor, a beam of infrared light that stretches from one side of the door to the other, will cause the garage door to reverse course automatically.
The increased peace of mind such features provide can not be underestimated, especially when we look to history to consider the alternative.
