Well, these are the ones I am looking for:
Hella 002395801 7" Round E-Code (ECE) H4 Conversion Headlight Kit
The only thing I am not sure of is the H4 bulbs themselves. It does not say what kind it is, if it is 60/55 watts, og 100/90 I think some are. It is the 60/55 watt I am looking for. The headlamp switch hold, just barely, but no trailer towing at the same time. I plan to get a set of relays and mount under the battery tray, that way they are out of the way.
The bulb socket for a regular sealed beam and the H4 are the same.
On all my American cars in Norway I have done this conversion, and it is like night and day.
