This one does not seem to have an answer?? My problem is basically the same as nath's with the addition of the cabin lighting at night!!

During the day you can mess around with the switches to get the relevant external lights to work as they do not seem to be linked to their relevant switch's but at night they "do not" work, cannot be seen from external view?!

Also at night there is no interior cabin light!! Although this is selected as either green or red within Aces. Is this an FSX thing or do we opt for reporting as a bug? Or is there a hidden switch somewhere? All the dials on the pilots left side do is turn on the actual gauge back lights.
