is there a bulb behind them, can the color be changed? my HU has a green/blue display and it would be neat to have a blue guage setup. or is it the actual plastic where the light shines through red?

another question i had is, has anyone ever tried switching the climate control ***** and their cd player. it would be nice to have my cd player on top but i don't think the holes in the dash are compatible, but what if you took a cd player adapter that was the same size as the climate control stuff then could it be possible?

I've seen blue indiglo gauges for sale on eBay, that'* your best bet. The gauges don't use red bulbs, they have red plastic built into them.

As fuddy sez, your best bet is to get the aftermarket kit, which are overlays that you stick on top of the existing dial faceplate.

Yeesh...

Realistically? No. I mean, sure, you can do anything with enough time and patience, but you'd be looking at a lot of dash reconstruction to slog through in order to do it. IMHO the amount of effort required would be wildly out of proportion to the benefit resulting from it.
