Yeah that sounds like a bunch of work just so you get to use an LED... sticking with incandescent sounds like a better path.
What if I want to make all dash backlighting red like a 90s Pontiac?
I need some more qualifiers around this. Is life otherwise normal? If so, 1996 it would be:
Daily: Saturn SL2
Street machine: Firebird Formula WS6
Truck: Mazda B4000
Offroad: Jeep XJ
Family hauler: Impala SS
That'll be a nice addition.
Only thing that worries me about a special part like this is the availability... I guess a stock one would work in a pinch.
