Brad, First I want to say that I've thoroughly enjoyed having your gauges in my car. I'm glad that you have created some really neat aftermarket items for our cars. I initally wanted the indiglo gauges when I first found out that you would be making them and then decided to get to go w/ your replacements in the meantime, mainly because of how everyone on here gave them such rave reviews!
Having a some electronic background myself, I do know that if you are talking about using the proper size inverters and such, that you are producing the "real" deal indiglo, and there for costs more to produce. I'll definately be on your purchase list if you do decide to produce them. I've seen your work and I know you stand behind it. Not only that, but you were more that understanding when the gauges I ordred didn't fit my cluster!! Thanks for the help!

BTW... Have you tried
Mouser Electronics ? (800)346-6873 They have a very large selection of electronic components and will probably have the inverter you need!
