LED rears became standard mid 2010, the LED "fairy lights" were an update to the option Xenons early 2011 i think.
Just to update, iirc the front LED's on factory fitted Bi-Xenon's came into effect in mid-2010 (any new pre-orders of March-ish 2010).
I ordered mine in April 2010, but was convinced by the wife not to go OTT with options thus no Xenon's (

), why did I listen to her !??!!
Got mine with standard fronts but had LED rears.
A neighbour collected his in Sep 2010 and had the LED's on Bi-Xenons, but unbelievably had non-LED rears. I still don't know why this was. I suggested that he ask his dealer but he couldn't be bothered
