I have one of those gauge overlays that you see on ebay, not the indiglo ones but the one that allows you to change the color of the overlay. I got this with my car and never installed it and it has just been colelcting dust in my room. Pics are here and here it also comes with the relay box and all needed wiring. Give me an offer. I'm sure these will fit on different years/models but make sure.

 

I'm interested, but not sure what it looks like when turned on. Does the whole background light up and what colors? Also the last overlay I had looked great in the day but at night was very blury.

 

ebay sells this same thing. In there ads it'll show what it looks like. I really don't know too much about it other than the overlay changes colors with a little control pad.
