I want to change the lighting of my instrument cluster from the normal blue color to red. I dont want to change the whole cluster though, just the part that makes the blue color. Is this done by blue lighting or is there some kind of blue fil under there that does the effect? I also want to do this with my A/C buttons. Is it the same for both or are the buttons different? Has anyone here done this before and if so, how did it turn out?
