If there's an emergency, Batman will be there in an instant – and if he's not, the Gotham City Police Department can simply call him using the Bat-Signal. Now you can do the same. Because even the overpowering darkness, when you actually want to read another book or comic, is an opponent to be taken seriously.

The DC Comics Batman Bat-Signal Reading Lamp looks as if it came straight from Bruce Wayne's personal stock of technical gadgets. In fact, it can be attached to the book itself, as well as to a thin shelf, bed frame or similar. And thanks to its batteries (not included), it can be taken anywhere. You can adjust the flexible arm so that the Bat-Signal lights up exactly where you need it – whether on the pages or on the ceiling. Supposedly, it also scares off nagging parents or flatmates who want to persuade you to finally turn off the light! ;)

By the way, Batman also likes to help you organise your books on the shelf with these Bookends.
