As I see in Etka, for cart to 11.01.2016:
LHD Part Numbers(England, etc.):
Left Headlight - 5G2 941 005
Right Headlight - 5G2 941 006
RHD Part Numbers (Europa):
Left Headlight - 5G1 941 005
Right Headlight - 5G1 941 006
And for cars after 12.01.2016 - this same part number but with letter E at the end.
