Has anyone put LED's in their climate control, if so what size LED's did you use and what resistors did you use?

That's the setup in my 2002 Corolla. For the climate cluster, I used 9 LEDs total:

-Around the temp knob there are 2 blue LEDs (rated 3.2v each) and 3 red LEDs (rated 2.1v each).
-Around the fan knob there are two white LEDs, and around the vent selector there are another two white LEDs (all white LEDs rated 3.2v).

These two branches of resistors are hooked up to the +VCC source that the original bulbs hook up to (observe polarity, check with a DMM), with a 100-ohm resistor in series with both branches to limit current in case battery voltage jumps above 12v (as happens when the car is running).

The AC, defrost and recirculate buttons all have their own LEDs, one white to light it (with 3.2v white LEDs, I used the single LED and a 560ohm resistor to hook up a single LED to a bulb power source) and a red as an indicator.
