Here are the numbers off of the sticker on my driver's side Adaptive Xenon light:

1ES-224-487-23/AC
7 164 461 01
SAE HR-HG03

And the raised lettering on my passenger side plastic shroud match yours
224-584-00 RE

As a side note, I looked at the window sticker from X5 and it says the following:

"Xenon Headlights: $ 800.00
Adaptive Light Control Included"

Logically I would think they would install the adaptive ones by default as they seem to be standard these days and are probably more plentiful.

Hope that helps you out.
