Changed my interior lighting a bit (Rex '04). Mainly followed the ideas outlined here:
... (thank you, Sisqocqk, for great job) but with some modifications.
Ignition switch I ended up putting part of a blue baloon on the tip of the blue bulb for a result I liked better. Used a 74 from row two.
HVAC I ended up using 74s, instead of 194s. Less bright, but worked for my interior. Used 74s from row one (on merchant site.) I sanded all these leds.
Fog light and cruise control I ended up with two blue baloons on each -- plus scraping away green film with a screwdriver. A bit messy, but seemed best alternative for my objective.
Dash lights: Used blue 74s from top row. Sanded all these. A bit dim. Didn't like how the odometer turned out -- with a bright spot in the center. Using a baloon on top didn't help. Ended up putting original bulb back in, but with two blue baloons on it. End result on the odometer had some teal too it. Not thought of a better solution yet. One problem I have here is that the red needles do not light up (noticably?) anymore. Anyone come up against (and solved) either the needle or the odometer problem?
