I just bought a set of procarparts indiglo gauges and I am getting ready to install them in my car, my only problem is that I replaced my factory bulbs with red colored bulbs. Will this change the way the indiglo gauges look or will they be ok?

It will change the way they look, because the needles will be red instead of greenish-white. >> I'd change the bulbs to the color that you want the needles to be.

I'm not sure that it matters but, when i did my indiglo's the only thing that the bulbs affected was the color of the needles at night. Did the guages come with a little controller for brightness? If it did, then chances are the technology used to light up the guage will not be affected buy your modded bulbs. But your needles will.
