Maybe it works for Steam and not for FSX since you are using FSX-Steam version of Captain Sim 707 and I am using regular FSX version of the plane??

Due to a  failure of my Thermaltake 750 watt power supply, that killed my 4TB HDD, I bought a 550 watt power supply, which is not powerful enough to run my PC with the Blue-Ray RW. Because of that, I haven't reinstallled FSX/Acceleration (FSX Gold). I  know the cabin lights worked in FSX/Acceleration, and if there is anything not going to work with the 707, from my experience, it will definitely be in FSX-SE.
