Here's a cool Xbox 360 mod
that won't set you back a bundle if it doesn't work out - only the price of one controller. With this Xbox 360 Controller mod, you can make your Xbox 360 controller buttons light up with LED lights matching the buttons' colors. This is a multi part mod, first changing the color of the LED's on the circuit board then adding 4 always-on LED's to the 360 dome, followed by lighting the start and back buttons, ABXY button lighting, and the rumble motor configuration. Not for the feint of heart, but definitely a cool result in the end!
