local light sources
which windows are you running?, I've had problems with local light sources but it was a long time ago and I'm trying to remember how I got it working in Vista but I don't think its an Orbiter problem have you tried messing about with 3d driver in Video I run full screen with 32 colours with Direct3d T&L HAL.
try messing around with the settings The ShuttleFleet Bay lights run fine and I have them on all my missions
