A-10A cockpit lighting changes when switching from Nav mode to A/G mode

First image taken in "Nav" (pressing '1'). Second image taken immediately after, only difference is I pressed '7' for A/G mode. Cockpit got darker when entering A/G mode.

OK. I'm having a hard time getting it to show up in the forum post after linking through imgur. But trust me, it's there.
