I have a Razer copperhead and want to change the color to white LEDs. 1. This one seems relatively easy easy to do, is this a 3mm LED though? Lights the mouse wheel. 2. i have circled three free connectors, could I put some 3mm or 5mm LEDs? Anyway to replace the LED at the front (the white thingy) with a standard LED? 3.The icon LED. It dims and brightens smoothly. It is a very small LED, which should I use? any help is appreciated as always!
