What about aircraft.cfg or panel.cfg??  Could there be an error in that? Which sentence in aircraft.cfg or panel.cfg is responsible for night passenger window light?

If there are any lines in the aircraft.cfg for the passenger cabin lights, I would think it could be these in  the [lights] section:

light.7 = 10, 55.00,   0.00,  6.30, cs707_vclightred
light.8 = 10, 52.46,  -0.30,  7.54, cs707_vclightred

Because according to the FSX SDK, the number 10 is for Cabin lights, but the cabin lights are not red. However there is a red dome light in the cockpit.
