C206G Stationair dash panel and dome lights?

I must have flown my C206 for the first time at night, and was not satisfied with the interior lighting. The panel lights and cockpit dome light seem to be tied together. By this I mean I could not turn on one without the other, and both knobs do the exact same thing. I did notice that the panel lights come of first, followed by the interior dome light a second later. After looking through the manual I can't find a solution. So my question is am I doing something wrong? If not, is there a way to remove/disable the dome light so I can see outside at night? I really only need the dash panel lights anyway. Thanks.
