Interior dash lighting

[JenSonEliCal]

I would like to change the interior dash lighting to blue...is it hard to do??

I only want to change the trip computer, stereo, and heating control lights...I'll leave the speedometer as is.

Any help would be appreciated.

Unless you want to tear apart your whole dash just to change the lighting on the trip computer, it's not worth it. The stereo and heater lights can be changed. Hope you have good soldering skills as you have to replace over a dozen very small LEDs on the circuit board. There is a write up on the mazda3 forum.
