I'm working on the same thing right now, with BB's help.

BB did my cluster and HVAC, and I'm doing the rest.

Somewhat a how-to. This is the first switch I did since the bulb was burned out. This is for the Chevy Impala/Monte buttons, so for the Pontiac buttons YMMV.

Our subject:


Cover removed (simply snaps on):


The original bulb in its blue sheath (the bulb glows a weird color, so the blue sheath was used to give it the right color from the factory):


Closeup of removed bulb:


Pulled back shot so you can see just how small the components are:


New LED and resistor:



Initial testing:



In the car:


Factory colors:


Back to the other side:


I've gotten a lot more switches done and I'm waiting on more LEDs and resistors to arrive.

Hope this helps. The resistor value depends on the Vf of the LED.

If you guys need more details in the writeup, just ask and I will go back and edit.
