So, today we were visiting our local Tesla show room and I had a chance to check out the part numbers for the new sun visors for the EU market. Interestingly, I was not able to find these part numbers in the public Tesla Parts Catalog, so I guess this will be quite valuable information for EU drivers.
One more interesting thing I was able to see: One of the Models S displayed in our local showroom did have the standard, cloth headliner. Since the new sun visors with lighting do only exist in Alcantara, this Model S did feature Alcantara sun visors in combination with the cloth headliner.
Here is the updated parts list:
BLACK Alcantara US/NA
ASY SUNVISOR LH ULTRASUEDE BLACK NA (1143824-86-B)
ASY SUNVISOR RH ULTRASUEDE BLACK NA (1143825-86-B)
CREAM Alcantara US/NA
ASY SUNVISOR LH CREAM ALCANTARA (1143824-87-B)
ASY SUNVISOR RH CREAM ALCANTARA (1143825-87-B)
BLACK Alcantara EU
ASY SUNVISOR LH ULTRASUEDE BLACK EU* (1143824-46-B)
ASY SUNVISOR RH ULTRASUEDE BLACK EU* (1143825-46-B)
CREAM Alcantara EU
ASY SUNVISOR LH CREAM ALCANTARA* (1143824-47-B)
ASY SUNVISOR RH CREAM ALCANTARA* (1143825-47-B)
*Since I don't have the part description, this is just my best guess.
The first 6 digits appear to be the same, while the 7th denote the driver's side (with a "4") and the passenger side (with a "5"). The next digit (8th) shows the region, "8" for US/NA and "4" for EU and the 9th digit the color, "6" for black and "7" for cream.
For comparison, this is how the EU Sun Visors look in "Cream" (white):
