Total kit for hi/lo HID conversion for an FZ6 would need to include: 1 H4 HID projector, 1 H7 HID projector, 2 controllers, 2 ballasts.
The HID kits from NewComDigi come with either 2 H7 projectors or 2 H4 projectors. You need one of each type from these kits - hence, the splitting of kits with another FZ6 owner. These kits come with the bi-xenon bulbs (6000k temp usually) inside the projector HID housings already. The HID housings also have built in angel eyes (with the color you order it in). The kit also includes the two controllers for the hi/lo beam function and angel eye operation. The only separate item needed is the 2 ballasts (either slim or regular will work) to supply direct power to the HIDs.
Hope this clarifies things up a bit.
