I am definitely not HiTech. He did give us the .sliders command. With clipboard up type .sliders, then move the std slider to the right. If I am correct, this should lighten your dials and give the needles and gauges the pop desired. Other than that, I believe that gamma is your best solution.
I also like the .sliders to darken terrain and trees a bit. Let me hear if that works. Oh, almost forgot..... default FOV takes care of the fuzzies and hard to read instrument dark areas.
