i've got an 02 model so pre face lift but the lights are still good, but looks to be a single light unit, so my guess is its bi xenon as well
my zed was a pre facelift as well so had the old setup, i tried swapping the bulbs out to a higher k rating, think it was 6500k made the light alot more white (had the faintest of a blue tinge to it) but i never found the light dispersion on the zed brilliant, they worked; but i always noticed when travellign next to someone in the dark on a dual carriage way that their light pattern would go further that mine.
always wished i had the facelift bixenons on my zed, they did look so much nicer as well.
thanks everyone for the help, its answered alot of questions and put the terminology right in my head
