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.

Thanks for valuable answer.  I am going to check to see if they exist in correct manner in the aircraft.cfg.
