The VZR ones are crystalier (what the hell kind of a word s that???). Heres a pic of mine (de globed with silver bulbs).
There is a catch though they're about €85+VAT and will take about 2 months to get here if ordered from Nissan. If you really want a set let me know. I can get hem cheaper and faster than from Nissan.
The differences between these and GTi's are, these have the bubble at the side as VZR's don't have repeaters, they also don't have the lines running through them like the GTi's.
