Making wing lights visible using wing views on SGA aircraft?

When using the wing views made for the SGA series DC-9-80 aircraft. I can see the strobes and nav lights on some and nothing on others when i toggle the wing views. When I do the outside aircraft views they're all working. Is there any number or something in the aircraft file to change so I can see them in the wing view? It seems to be the DC-9, MD-95 aircraft.....Thanks in advance........James
