Light Lock / Home Furniture

Light Lock

When you are about to unlock the door at night, is it frequent that you couldn’t find the keyhole because of the lack of light?
You could find the keyhole effortlessly with the aid of a Light Lock, fitted with a 30 centimeter radius
infrared sensor which, when triggered, would emit a beam of light through the keyhole, where you could thereby precisely spot and unlock.
