Light Housings, Part Numbers and Differences

[Version4]

Hello there, just curious as to what the differences are between these light housings:

8E0 941 003 BP

8E0 941 029 BP

8E0 941 029 BA

8E0 941 029 BD

They are all part numbers for a left housing. My question is, what is the difference between all three of them. I know they are all bi-xenon and all _should_ be auto-leveling. I also know that the 8E0 941 003 BP was superseded by the 8E0 941 029 BP.

Are any of these curve lighting? What about range adjusting (on the fly)? Any other differences?

Thanks for the help. I guess anyone with access to an up to date ETKA would have no problem getting the info.
