I've also done this mod (I posted a small write up on it in a thread back when) and I know the HVAC very well now. I could Rig up a dozen blue LED's and resistors to wire, and send them out to people relatively cheap. All you guys would have to do it take the 'rig' I send you, snip the old light off and connect the end of my wires to the wires that were connected to your stock bulb. The LED, wire, 330ohm resistor, and soldering are already done for you (by me).

Anyone interested? If so I will get to this asap, I can have them all done in a day or so. E-mail me if interested.
