Okay, I've got another car for the next 3 weeks so I've already torn apart my gauge cluster. I've got a lot of things I want to try out...

I have a question about color filters. Where would one buy different color filters? What is the specific name for this type of material? I tried some different transparent blue plastics I had laying around but it amazing how the back lights wash it out. So, I'm pretty sure there is a specific type material to do the job, but what's it called and where do I get it?

I'm going to try some brighter white / colored back lighting and I already know where to get this. Just need some filters that will work...

Thanks guys!
