This is a small light which can be useful in various situations. You can put the light and switch it on everywhere you wasnt. When you push one side like a switch, the opposite side stands up and shines. When you lay down the light, it sleeps and almost disappears.

This light through the Japanese metaphor of ‘‘役に立つ’’ [to be useful] simplifies the relation ship between a light and a switch. The light changes the mechanical action of switching it on into an action which is closer to a human action.
