Can custom LEDs in an xbox 360 controller be detected? if so is there a penalty?

[GodOfDesecration]

i just bought some LEDs for the A X Y B buttons, the guide ring, guide button, and start and select. i was just reading up on how rapid fire is detectable and you can get banned from xbox live if you get caught. i just want to know before i mod the controller if there is a risk when installing LEDs.

thanks,
