The Periscope® Book Light in a Bookcover for paperbacks lets you read in any light and in privacy no matter where you are. Whether you're on a red-eye flight, a camping trip, or curled up in bed next to a sleeping spouse, this is the perfect solution for readers. You'll never have to remember a separate light again as our reading light stores in the bookcover with your book. It turns on automatically when you pull it out of the spine and turns off when collapsed back into the cover. Wide angle, ultra bright LEDs light both pages, top to bottom, no matter what angle you hold the book.
Uses three AA batteries (not included). The deluxe cover protects your book and your privacy! Fits mass market paperbacks.
