Yeah the factory LEDs look clear, but when they light up, they are green. They produce light depending on the chemical makeup inside them. Just cut the old one off and solder the new one on. Keep the resistor that is soldered on the switch. That will still need to be there. The Anode side of the LED (positive) will solder to the resistor side. Thats how I did it. BTW, the size of the LED is 3mm. If you have any more questions, feel free to ask.
