Followed a 66 plate Superb Estate this morning and it had full lights on the back (i.e. lights continuing on the boot lid). I presumed it was an SE-L but when I overtook it, it didn't have the strip LED DRLs or Xenons.

 

 

In DK the "full rear lights" are standard from Ambition and up (think that is what you refer to as "SE").

 

Ambition does not come with xenons as standard, so - over here, at least - that combination is possible.

don't all the rear light look like this?

 

The early ones and lower spec models didn't light up the section on the boot lid.

For MY16 SE-L and above trim levels, the light extends into the lens in the boot.
