I want to change the light bulbs in all these areas to a different color, so anyone know the type of bulbs for each location. I think for instr cluster its type 74, but what about other locations ?

 

you have to use LED in other locations. Use 3mm LED in radio and 5mm LED in window switch and climate control.

I'll say it again.. the instrument cluster color is not sensitive to the bulb. It has a transparent layer built in that gives it the color you see. The bulbs are in fact yellow (standard wire bulb, no coating). The way to change it is to use high powered blue leds so you basically override the built in white layer..
