Stop in for a cup of coffee

I don't know for sure. I owned a pair like that and gave them away when I got the Hellas that meet US automotive standards.
If its that model, the noticible differences were the super sharp cut-off line, and when the low beams were aimed correctly, the high beams were too high - leaving a big dark area on the road. Stern posted a these isocandella diagrams of that Hella and the production Cibie (late 1990s early 2000s).

I just don't think you'll be that happy with those on a car.
7" Sealed Beam H4 replacement - ECE or DOT?

But Hella does make some other models/or has, and if its one of those, its probably better.

The cat's meow for North American use is probably Cinbie's "Bobbi" lamps and their "Z-beam" lamps; both long out out of production.
The Bobbi models had a sealed housing, and used an H4 or HB2 bulb.
The Z beam had a beam that steps up on the right like the VOL and VOR patterns, instead of angling up. I've got a set but haven't put them in yet.
There's a pair of used Z-beams on e-pay now for around 270.
New genuine Cibies are about 90 each or 180 a pair in the US/Canada.
Not cheap!
is there a huge difference between the Cinbies and the Hella's to warrant the cost difference?
