A door handle which becomes flashlight

No need to fumble in the dark looking for the door when you wake up at night or during a power outage. A trio of concept designer produced a door handle, LED Door Handle, which can see more clearly. LED Door Handle is, as its name implies, a door handle which has two LED lights, one at its base and the other at its end. The first uses very little energy and glows continuously to indicate the path to the door.
The second, detachable, can be used as a flashlight. For food, the illuminated handle operates the mechanical energy generated every time you open the door. It is equipped with a lithium battery.

This concept was devised by Kun-Hee Kim, Kei Shimizu and Nguyen Dang-Vu. LED Door Handle won a 2011 Spark Award.
