Ok, I successfully replaced my stereo and HVAC lights with blue LEDs but I wasn't so successful with the instrument cluster (search not too useful)...
My tach and speedometer are lit up ok but I discovered today that I can't see the needles at all when its dark out...kinda useless like that.
Also, I have bright spots when I replace the odometer light and in the fuel/temp gauge region.
I used the radio shack led + resistor approach. Has anyone used an alternative with better results? I don't want to use the reverse indiglo faces because I don't like the white color during the day.
