I think I'm going to try to change the dash color to green or blue anyway, because in addition to the Empeg, I am going to add an Eclipse (Fujitsu Ten) head unit which has a combination of blue-green and blue VFD elements. Besides the red filter for the Empeg is very dim, so I want to stick with a green, blue, or possibly smoke filter. Thanks to those links, I can start to plan how to accomplish the blue or green color change. I can see why the blue might not look good around the red areas of the instrument cluster. I thought that there would be discrete bulbs for each of the colors. I guess I will have to devise a way to isolate the various colors so they all look the way they are supposed to and yet turn the orange lights to blue or green.
