Fading Domelight

A capacitor has nothing to do with it. You need some sort of electronic variable resistor. Something like that.

Your application may vary but I was told by the dealer that the dimming domelight on a 2000 focus is part of the illumination control module. Perhaps someone somewhere has a wiring diagram of this part so we can all see how to do it. Hope that helps somewhat. :)

I have also been wondering how these fading domelights work. I was just thinking about getting whatever circuitry makes it happen out of a vehicle that has it, and then install it in my 92 Toyota truck. Would that not be the easiest way to do this?

That site you suggested was pretty interesting some cool stuff there. I will definitely be checking it out again thanks alot pal.

PS: The schematics were on point as well I think I 'll try fade away type circuit in my car as well.

For those of you that don't want to bother trying to build your own circuit...
