USB laptop light
If you're home alone at night surfing the web, listening to music or reading over some documents you will need some light to save your eyes some trouble. But you won't need the main room light on to get the illumination you need.
To effectively light the keyboard, USB lights are excellent. They slot easily into your laptop's USB port and the light can easily be directed for optimal results. Best of all they only tend to use up only two watts of electricity – now there's a bright idea.
