ive searched this term and i know how to change the led's fairly easily. what im still in the dark about is the backlight. i want the knobs, etc to be blue. how do i do this without painting because im afraid that will make it too dim? i read i need 5mm LED's with 220 ohm resistors, but i dont know where to put them.

if you do a red wide angle led with 1.7v & 20ma then you need a 1/4 watt (preferably 1/2w) resistor with about 550 ohms. they sell these things pre-made on online stores and ebay with socket and all. This is pretty expensive though.
