Making you sound like an idiot wasn't the intention I had when responding to your thread, merely the fact that I was trying ot help you out.
Okay, I just wrote 3 paragraphs, and deleted them. Starting over...
I was looking at the color changing needle kits on eBayMotors, and think that the needle kits would look better on BLACK stock gauges, not white faced gauges. Maybe, they would look pretty cool of white ones, but you would have to get white gauges that would glow BLUE at night, since you want to go with the blue color.
Now when I saw that they are white faced gauges that are blue at night, I mean you would have to look for the REVERSE glow kind, where the entire gauge face glows leaving the black silk screened numbers and lines black at night. Autometer and Indiglo have them.
Since the stock color on the gauges is green, I would consider this option above or change your mind and go with green needles instead. Or stay with stock gauges that are green at night with blue needles. It's up to you.
I also tried looking around my garage for the clear needles I had, but I must have thrown them out. Figures. I knew there was a reason I hesitated and thought about keeping them! Oh well.
Here are some pics of the needle kits I'm talking about. I've no clue what entails making the needles change color, but I'm going to assume all you are going to get with the kit are instruction of tearing apart your gauge, and replacing the stock needle light bulbs with the ones that come in the kit...
