Mikhailtech take a look at Antec’s iLuminate light kit
This "puck" is responsible for everything that makes iLuminate unique. Some cold cathode kits have motion sensors to match them to the beat of music or the sound of games, but these generally look awful and aren't very practical. Antec took a different approach. This cylinder is meant to be placed externally, directly next to a sound source (such as a speaker or a sub) for the best effect. It connects to the PCI slot using a PS/2 style plug. This slot has three settings. "Light on" means the tube is constantly glowing, whether the controller is plugged in or not; "off" is the master switch for the whole thing; "control on" hands things over to the puck. The puck is basically a cylinder with a switch on the side and an adjustable knob up top. The switch has four settings: "off/on" are self-explanatory; "fla" makes the light constantly flash about twice per second; "mo" activates the motion (sound) sensor. The blue portion acts as a knob and adjusts the sensitivity of the unit.Read more
