Thought the product site claims that the Mobile Light “is a mobile which emits light”, I like to think of it more as a simple LED light stick. What I absolutely love it this horn-like thing is that is completely solar-powered which means that its super-green and that it automatically starts emitting light as darkness falls so you do have to hunt for it with the faint light of your cell phone! I also see a lot of potential of using the light stick as a self-protection weapon for ladies who have to travel back in the dark from work!
