Tinting the whole lense would likely be the easiest for the gauges. It's a removable piece you can tint from the inside. You can use the same tint on the inside of button housings to tint them red. Lamin-X will work for all Applications mentioned. If you didn't want to unclip the lense you could tint it from the outside too with similar results and protect the lense from scratches.
