I am getting a new audio system installed in my '99 Contour, but it will have a blue display. Everything else as far as gauges (including the heating/cooling gauges) light up green at night.

Can this be changed by putting in different bulbs behind the gauges or is the green color "molded" into the gauges themselves?

I have been thinking about some of those gauge overlays, but first off, I can't seem to find a good place to get them for the 1999 model year that HAS the tach (not SVT), and I would like to get a matching one for the heating/cooling gauges too.

Any ideas?

Thanks!
