In particular, I am looking at the Logisys CLK15WT 15" White Deluxe Sound Activated CCFL Kit. From what I've been reading, the light is supposed to pulse when it "hears" a sound from an outside source. Is there a cold cathode light that is activated by sound that could connect to the mobo or some other device that wouldn't need an outside source of sound? I would like for the light to pulse when I have my headset on and don't understand if the kit I'm looking at will do that.
