It's something that has been bugging me since day one, runway exit lights are all green, when in real life (and on x-plane) they are green AND orange. Orange lights are there in the SDK and I'm really surprised no one has come up with a solution for it. Even the hand crafted airports still have solid green (and often randomly placed & wobbly) on the exits/entrances.
I've tried sorting out my local airport in the SDK but I don't really know what I'm doing.
Also how can this have been over looked? Surely the devs know about it? IS anyone able to sort this out?
