I trust you are aware that the instrument lighting level is adjustable through the indicator stalk button menu TimG? It goes from 1 to 10 and 10 is pretty bright. I have found about level 6 is OK.
I wasn't, although I think I knew there was much magic (and potentially, damage) to be done in those hidden menus. If there a quick crib-sheet around for the 'keystrokes' somewhere?
