The next time you see your loved one’s photo on Facebook, take a moment to recognize that someone else took a photo with a flash light on.
This is called a light source.
It gives a person in a wheelchair a better view of their loved one in the photo, the National Institute of Neurological Disorders and Stroke said in a press release.
But, the flashlight also has some drawbacks, like its low power and the lack of a backlight.
You can find a flashlight at most hardware stores, but if you have to go to the store, get it at an electronics store.
