@Mark Thanks for the detailed response
Certainly looks quite dark I agree - perhaps it shouldn't be brighter in game. Just a tiny amount brighter would certainly makes things a bit easier at times though - always tough to fully recreate what an eye captures on a photograph or in a simulation.

The two course knobs having a light-outline helps make the overall darkness not a problem, as you can still easily find the knobs.
In the same vain, the top of the frequency knobs on the left seem to be slightly lit from the NAV-frequency display. Just that slight light would also help in finding inner/outer knob. No problem with darkness if you still have some way of locating things.

Fully understandable that it is though to reproduce the piano keys perfectly in the sim. Was more just an extra little detail I noticed when looking at real life videos.

The steps to reproduce the issue are the following:

Switch the radio panel on with the rotary knob Turn on the nav light in the alpha flight yoke The radio panel goes out and you need to switch off the nav lights in the yoke to turn on the radio lights with the rotary knob
