Actually, it appears to be a vacuum flourescent display, which are tough to find in red. You can tell because when they turn on or off there's a little bit of a lag and they fade in and out, whereas an LED is instant. I've seen them in kind of an amber color though, but the wiring inside and the illuminating shapes are application specific. They work with matrix though, and it shouldn't be too hard to translate it into the circuits for a set of 7 segment LED displays, or an inverted LCD which would make it look like the ones on an STi. I guess I'll have to pull mine out and give it a try.
