Most of you are familiar with the Xbox 360 and its innovative design controller. Yes, it is true that we have first seen this kind of gaming controller or pad first time with the Xbox 360. Before that there wasnít any kind of development in gamepad or controller. They were looking very classic. However you might have also seen different color light on the keypad or on buttons. I want to know what kind of light does the Microsoft actually used in it. The light looks very different from one gamepad to other one.
