Been doing some research on these lights.
As folks have said,
H7 = FTP
9006 = Fogs.
What you'll notice is that on Amazon you'll have 10 vendors selling the same bulb but changing their description of the product to differentiate their product from another vendor selling the exact same item. Thus you find the regular 9006/Hb4 bulbs at 13.94 and the exact same bulbs but with the "JDM" tag added on along with the higher price of 18.95. Same goes for the "arctic yellow".
Nokya only makes one H7 bulb in Hyper yellow (Nok-7610) and the 9006 bulb (Nok-7616) Nokya does not make Arctic Yellow, or JDM Yellow. Simply Hyper Yellow bulbs.
Oh, one last thing....watch out for shipping. I just went to purchase both sets and the entire purchase was 22.00...and the shipping was 20...for regular old ground shipping for some bulbs that weigh less than a pound and take a small box. Rip. Off.
Keep that in mind when making a purchase =)
