Better way to backlight your rallye cluster, or any gage cluster for that matter, 5630 LED strip lights. You can get these in many colors. They are dimmable, as well as some having fully adjustable multicolor capability so you can change the colors to suit your mood. I went with green, but even purple is available. Cheap too. Evilbay, about $5 for 5 meters, or about 15 feet. This will eliminate the bright and dim spots and make the lighting more even throughout the cluster. Bonus LEDs dont burn out easily, and the pics shown were lit with a half dead 9v battery on my bench showing just how efficient these really are
