Hidextra H7 plug and play?
Are they plug and play with stock bi-xenons ?
Are they safe to use?
I'm also a little confused because on there website they claim the 6k is the brightest bulb they have but from my research it seems the higher the k the less useable light.
Any insight would be great!

I've used hidextra before with no issues but I would recommend getting OEM bulbs such as philips or osram
