APM-lighting system is one of the features that comes with the StarCraft 2 gear of Razer - a mouse, a keyboard and a headset.
The "Spectre" mouse, the "Marauder" keyboard and the "Banshee" headset are all parts of the newly announced StarCraft 2 gear of Razor. The gear comes with a unique StarCraft 2 design with a standard blue light, but you can custom it the way you like with the new APM-lighting system. The APM-lighting system can be used to see the level of your APM through a different color on the light, in example; you're having a low APM and the light on the keyboard, mouse and the headset turns green. But when it goes up to say around 300, it will turn red, and some other colors in between to let you keep track on your APM while you're playing.
The Spectre mouse will cost $79.99, the Marauder keyboard $129.99, and the Banshee headset $119.99 and will be for sale soon. Read more details on Razer's official site in the link below.
