Right, I just replaced the bulbs with regular stock replacement white bulbs. The thing about colored bulbs behind the guages is that the blue color in the guages is produced by a material of some sort inside the guage cluster itself, not by the illumination bulbs. So the colored light that is emitted from a colored bulb would have to filter through the blue backing of the guage cluster, hence changing the overall color seen in the guages. So if you threw a bunch of RED bulbs back there, the light you saw in the guages would be some combination of red and blue. It might still look OK, but I don't know, I haven't tried it. Besides, I haven't found any GOOD and INEXPENSIVE colored bulbs that didn't lose their color and turn white eventually anyway.
