Switch Lights & Interior Illumination

[DieselFitter]

Dear Diesel Fiends:

Please forgive me in advance if this topic has been covered already - I did a few searches and couldn't locate the info I need.

First: I own an '83 300D and have recently lost illumination on the set of four switches to the north of the Climate Control panel. You know the ones I mean: rear courtesy lamp, antenna, sunroof and defroster. I seem to recall reading something about these switches sharing a common source of illumination - is that the case? And how do I get these switches out and replace the bulb or bulbs?

Second: I've read many posts here about the lackluster quality of instrumentation lighting on some MB models, mine included - but am I alone in believing a dark passenger cabin is not necessarily a bad thing? One of the reasons the dimmer's there is to turn things down, right? Have you ever been driving on a dark country road and noticed that interior light "pollution" is making it difficult to see outside the car? Personally, when I'm driving in an area without street/highway lights, I turn my interior lighting WAY down to the point where I can just make out the speedo.

Am I nuts here or does anyone else do the same?

No Xenon instrument bulbs for me,
