Autogauge gauges - led colour?

[C.A.R.]

My car came with a boost gauge already fitted, which is nice. I plan to move it to an A-pillar pod (any recommendations?) eventually.

I'm a big fan of keeping things OEM where possible, so was wondering if you could change the led colour in the autogauge unit, does it come apart?

At present it just lights up blue and red. I want it to be amber!

I might go the whole hog and order a different gauge, does anyone know of a decent gauge with black background and amber illumination? I've seen there are Prosport ones for like £40...
