Stop in for a cup of coffee

@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.
It's one of the faults of that particular lamp. On a vehicle with higher lamp placement it wouldn't be as noticible, but I'd still not use it in preference to a Hella "vision plus", or any number of other options. I'm not the only one who has observed that split in the light pattern as some of those links showed. It's not just people's subjective perception, its showing up on the test equipment. Is it better than most lamps sold at parts stores and on the internet? Yea, probably. Would I use them over the GE Nighthawk sealedbeam. No!

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.

Twenty-five feet is what was specified in the service manual for visual aiming if a headlight aimer was not available. Then aim as follows, using the first part for hi/low lamps and the second part for dedicated high beam lights.

That's what the Virg. regs illustrate.

NJ and some other states would check the aim using a machine at the annual state inspection.

As far as I know ECE lamps have use a similar distance, although surely its not in US or Imperial measure. LOL. Headlamps positioned higher on vehicles need to be pointed slightly down. On the Hella H4's that don't meet US automobile standards, this is what I followed. Same for ECE Cibies on my Grand Wagoneer.

For the Visionplus Hellas I've also visually aimed them, but back when I started using them, the car was still registered in NJ. So the aim was checked and corrected if needed by machine. Too long ago to remember if they had to be readjusted.
