Is there a e-book that lights up so you can read at night?

The iPad, the Kindle Fire and some versions of the Nook have a backlight for this purpose. There may be others. Or you can get little lights that clip on to the corner of the reader. At least some of them draw power from the reader's battery, so they don't need one of their own.

Kindle fire, nook color, nook tablet

idk...
