I am very interested in doing the LED upgrade... but the price is still scary... and since no one has ever been arrested for using Hella's, I will continue to do so.

I am curious... why do Hella conversion say "US DOT LEGAL" on them if they are not legal?

Be aware that some C4s use the headlight filaments for the ground path for the fog lights. The fog lights will not work with LEDs or HID lights unless a separate ground is connected.

Where can this information be found? I am interested in seeing the schematic for this one.

There's another LED light thread from about a week ago that was discussing this very issue. I know my 96 has this issue with my LED lights, I have a possible fix I'm going to try but it'll be another week and a half before I get back home to the car to actually give it a try.
