There are a few variations of the dome lights in this car, though, so maybe you would have better luck. It might be easier to install 2 of the passenger-side moonroof model overhead lights, as there is only one button to allow it to be turned on, but otherwise controlled by the main light unit.
I don't have the moonroof. I do know what you mean and I can see that being an issue with the moonroof since there is a light on both sides of the moonroof. Mine only has the one central light between the drive and passenger, and then the rear seat light, which has no controls on it. Those both come on when the doors are opened.
