I've been looking around on here and seen some GREAT ideas that I will follow thru with on my own car. The colored bulbs and LEDs on superlumination.com are a great way to add something to the car. My question is. Is it possible to change the bulbs that luminate the dash and guages? I know superlumination.com has several different bulbs listed. I bet they can be changed out. I was just wondering if anyone has ventured into this customization.
