Sometimes when I look at the Amazon Electronics bestseller list I see a harmless looking book light on the number two spot (right now it just disappeared again). The top spot has been reserved for the Amazon Kindle for a very long time.

Apparently the Mighty Bright XtraFlex2 Clip-On Light is the most bought Kindle accessory. Kindle does not have a backlit screen, but paper books do not have one either. I never use a book light for reading, but Kindle owners do. I guess most Kindle owners read in bed with their partner sleeping next to them.
If you need a light for the Kindle than the Mighty Bright XtraFlex2 Clip-On Light is the one to go with as it has a flexible neck to adjust the angle the light hits the screen for avoiding glare.
The Mighty Bright XtraFlex2 sells for $15.25 on Amazon.com.
