Just A Bit More: With your new XKGlow parts, you may need to either split a circuit or extend it, and these components allow you to do just that! 2-Wire Single Color: These components use a simple power/ground two wire circuit. No color changing stuff here, all 12V goodness. 3-Wire Million Color: The base RGB line from XKGlow, the 3-Wire RGB circuit of the Million Color components are still able to provide almost any color in the spectrum. 4-Wire 7 Color / XKChrome: The ultimate XKGlow moniker, XKChrome provides all the control you can imagine--and in any color. These 4-Wire setups are also compatible with the older "7 Color" components.
