To ask for this feature is one of the reasons I joined the forums. Playing at first with all the excitement I didn't notice it, but after some flying while trading I did notice it's really dark most of the time inside the ship because you only get light while near a star or inside a station. I understand bright lights inside would make harder to see outside, obviously it would be a toggle option, you don't really need too much detail outside while working a trade route and you just shut them down when you need to do precision flying. Also it's probable the lack of light isn't that noticeable while in a Sidewinder or an Eagle, but in the Hauler or the Adder that have bigger but more closed up cockpits it is, and I feel I can't really enjoy the detail of them most of the time.
