LOU is on the mark, night lighting is a personal thing to a degree but some aeroplanes had better lights than others. Me, I liked it dark and put on the overhead or map light to read a map or chart when required. I once flew with an old crusty captain who liked it all up and as bright as you could get it, used to drive me crazy but I appreciated his technique when operating in bad weather which we used to do at low level doing maritime patrol and the radar is painting red and purple, when you down at 500ft over the ocean on a dark and stormy night going this way and that as the radar controllers up the back vector you onto a ship,you wanted to see everything and very quickly when the annunciator panel lit up with a red fault in driving rain and crap turbulence and I used this technique in these sort of conditions but on the cruise home at flight levels still liked it dark and quiet.
