Ive also had a look at this with the Hamilton x runway ,just giving a little light on a night map texture for the runway ,does help abit to define the runway as you come in, the taxi aprons are done the same with little amounts of light under the lightpoles etc, giving it a over all lights are on look .
im not sure how this could be done with FSX default textures or even if it would look ok ,there are alot of addons that enhance these features ,even playing with the default runway lighting effects in notepad could brighten things up ,you just never know what will work best until you try mucking around ..
"Warning "always back up the files you are playing with ,saves alot of problems down the track ..
