In case you always wanted to read a book during the night without disturbing other people with a bright light, what you really need is the Ear Light.

This LED light is supposed to be placed on your ear (like a bluetooth headset for your cellphone) so you have free hands all the time to do what you want. Besides the reading-in-the-dark scenario, it can be used in other situations, so just use your imagination to come up with something useful.
