Downrange, If i choose to go with that Morimoto package what Adapter plate, bulbs and what wire harness? Oh also what is the CCFL (sorry I'm really new to this)
I'll try to answer your questions.
Adapter plates: These plates physically adapt the HID projector to the motorcycle's light bulb sockets. Due to the design of the FZ6 headlight assembly, you need one on H4 adapter plate and one H7 adapter plate. (You may have to contact them to order two different adapter plates for one order.)
Bulbs: This is mainly the color temperature of the bulb. I would go with 4300K as it produces the most usable light output. (I went with 4300k and love them.) The higher the number color temperature, the more purple the light will be, but the will put out less light output the higher number that you go. My 4300K bulbs are just really white, with maybe a tinge of blue and I like them that way. The other bulb option that they offer, is for their upgrade model XB35 bulbs. You'll have to read the description to see if it would be worth the extra money for them, but I personally wouldn't get the XB35.
CCFL Angel Eyes: These are the colored rings around the outside of the projector that can light up. If you hang out in the parking lot with your key on and your headlights off, they would look cool. I have them on my bike and you basically never see them, since I don't sit around with my key on and my headlights off.... I think they aren't needed unless you want the bling. Save the money and extra wiring hassle.
Projectors: Stay LHD if you're in a country where you drive on the right hand side of the road, and the steering wheel is on the left side of the car. This option selects how the beam cutoff is made and where light goes and doesn't go.
Resealing Glue: I don't think you need it. My kit came with it, but there was so much glue left on the housing after oven time, I didn't need it.
Shrouds: Decorative covers that go over the outside of the projector assemblies. You might not even need them if you're going for the black look. Otherwise, just go with the standard mini gatling gun. You need to be concerned that you don't pick a shroud which will be big and cause fitment problems in your headlight assemblies.
Wire Harness: This is wiring plug type that the lights will use to connect to your motorcycle. I seem to recall with the FZ6 that you need to choose the H4 connector, but I also recall having to do some manual wiring due to the way that the high beam works on the FZ6.
I hope that helps you some.
