Here's some more detail on the problem. To get the Euro headlights to work, I disassembled the regular US headlights and took out the wiring. Then, I moved the connectors (high beam, low beam, and ground) around inside the white connector (to headlight bulb) to correspond properly with the H4 bulb. I haven't driven the car at night since I did this, (strangely enough) and tonight I noticed the problem. The foglights work fine, but I'm a bit worried about getting the high and low beams to work properly.
