Here's an idea...
With all the improvements nowadays, pilots tend to start using HUD (Head Up Displays). You could build an eye-sensitivity-meter so when the pilot identifies himself to the system (the aircraft), it would measure the pilot's eye sensitivity and auto regulate the cokpit lights and annunciators. It would also recognyze the problable lighting conditions on every moment of the flight, by considering the aircraft's geo-position, its altitude, its relative position to the sun and so on... You could also propose a modification for replacing all of those tiny (there are hundreds of them) little lamps for the annunciators by LEDs. With the proper intensity regulator, of course.
This can be looked as a joke, but then again, think again. You have no use to build a system for today's environment, specially if the job can take years.
So, it all depends on how much time are willing to apply on that work. The more time, the more far ahead you have to look and maybe, guess...
Hope this helped.
