I was wondering on this led mod. Do you really need to add a resistor if your using a 3mm blue, pink, white, or green led ? I know for sure you need one on a red, yellow, or orange led, cause it will be too much voltage going to the led, since those leds are usually 2.1 or 2.2v, and will burn it out. ( experience on that lol ) On the xbox 360 controller, you don't need a resistor on the blue, white etc.. colors. Just wondering, I dont want to burn this ones that im doing lol. Thanks...
