Totally confused with these Xenon bulbs
And shocked that a single bulb cost a few pennies short of £50 for a D2R.
What confused me was when I was asked what colour I wanted
Also told by local motor factor that these bulbs are non returnable once purchased???
So here is what I've found out from the internet.
Color Temperature:
 
3000K(Golden Yellow)
4300K(Sunset yellow)
5000K(PURE WHITE )(VERY CLEAN)
6000K(Diamond White)(HAS A LITTLE HUE OF BLUE, POPULAR CHOICE)
8000K(Iceberg blue)(LIGHT BLUE BUT STILL GIVES OUT GOOD AMOUT OF LIGHT)
10000K(Brilliant Blue)
12000K(Exotic Violet)
30000K (Pink Violet)
So any one know what K values are fitted to a 2005 350z & 2010 370z.
