More good news! The part came in I was waiting for to make the LEDs for the needles actually change color mid-sweep! (Instead of having to leave one RGBIC LED on that color) Now, let me explain: when the needle sweeps to a set point on the gauge, a seperate LED (for most people it will be red, but it can be any color only chosen once) will illuminate and therefore changing the needle color. The LEDs already illuminating the needles won't be affected. For me obviously I want bright red so as to signify warning or danger (I don't wanna get a heavy foot and blow the welds on the intake

I haven't fully assembled and tested it inside the cluster yet, but part does work exactly like I wanted when bench tested. But... downside is it's looking like I will have to make a small hole (about the size for the needle stop peg holes) in the overlay for the sensor so it can read the needle position. Not a big deal for me
