I have a question about how dash lighting works in cars, at least in general. It is my understanding that most cars use incandescent bulbs with a filter in front of them to create the illumination color seen on illuminated button labels and instrument panels. If I wanted to match the dash lights to the color of the empeg and my future eclipse head unit could I not just one-by-one replace the filters in front of the dash lights?

If anyone has tried changinging the color of there dash lighting I would appreciate your input.
