@Mattax, I have no idea why you experienced this with the low beam adjusted correctly, and experienced the high beams to be too high. It did not used to be like that. I have had many of these conversions, and all of them have been fine. But, I have seen the examples you mention, but not on my own cars exept maybe my Mercedes W123 series. But it did not have sealed beam style headlamps at all. Now, it is obvious that you can not adjust the low beam as it should be, and then adjust the high beam later, unless you have 4 lamps but that is a different thing. So, it must be some error in the production that causes this. Then, when you say you adjusted them correctly, I don't know what that means. I always adjust them against a wall, with the car 15 feet from the wall. And the height of the cut off line on the wall at 90% of the height from the road up to the center of the headlamp. That means the low beams will shine 150 feet forward, and that is what they are made for. Some extends it to 16 feet from the wall and still 90%, but then I suspect you start getting a darker road with high beams. In the older days I think they used only 13 feet from the wall, which gives 130 feet of light with low beam. The cut off line on the ECE lamps are supposed to be very sharp over on the wall. A straight line to the left of the center of the lamp, and then a 15 degree angle upward light, and then you have the same pattern over at the other light.
