This is an OEM Xbox 360 ring of light board modded with 0603 LED's. This is drop in ready, take out your old ring of light board and install this one and that's it!. Necessary tools, 360 Case opening tool and a T8 driver (tools available separately) Note that this mod is a single color mod replacing the normal green with the desired color, the error status red is disabled so if you do get an error like the 3 red lights they will be the four black lights. Its pretty obvious when an error occurs and you can always plug your old one back in for diagnosis purposes.
