A neck light is precisely what it sounds like, a light that rests on your neck.
Most types are U-shaped, with an LED lamp at the end of each arm, according to an article published on The Verge, touting these gadgets.
The product can be found on Ali Express for a couple of dollars. One such store is the Bougielb Light Store. It is a hands-free, portable, rechargeable USB book light.
The lamp hangs from your neck, and the light is adjustable.
