Can be done, but its PITA!
This is the third set I've done. First set I ruined, but it was a learning curve. Second set was a JDM set, easier as less markers. Went the full hog with these. They light up red even without the lights on, and get slightly brighter at night.
The earlier HVAC dials are just a matter of changing the bulbs over, the later blob/hawk require some serious modding. Still working on mine as Ive a few bright spots.
And the clock....work in progress.
