You may have experienced trouble locating a keyhole in darkness at your door. The keyhole is so small and it is so dark, finding and putting a key in is almost always troublesome and annoying. “Lighting doorknob” is a doorknob designed for easy detection of a keyhole even in darkness. The doorknob collects electricity using solar cells during daytime. When the knob is touched at night, the LED lighting system lights up so that you may find the keyhole easily.
