Hid kit question please help

[Zetectdi]

I have recently fitted hid kit to my mk7 fez it already has
Projector lights as standard, fitted the h7 6000k kit
The beam looks very green at night when they reflect
Off cat number plates etc yet bright white when you look
At them on
Problem i have is they seem to show a dark line in the road
From each bulb rather than having a clear beam with no break in it at all
Also they seem like they are moving in the light
Is this normal??
Is there a right or wrong bulb or type you can fit in the projector??
And does anyone know the best for giving best night driving?
Bin told 4300k are bright white

Please please help its frustrating me gggrrrr

Thankyou
