They're dull because there is a green film backing the gauges where the numbers are. The film filters out light that isn't green, so only part of your blue, red, amber, etc light will come through, the green part. You can take the gauges off and scratch that off, as I did with my headlight switch, but normally, the adhesive will pull the black with it and it'll end up looking like crap. Simple fix, inidglo overlays.
