Probably genuine. I've heard about the Depo copies being 'ok' but only really any good in terms of light output if you use a HID kit with them.
So I'm thinking by the time you're finished faffing about and spending more on the HID kit, you might as well spend a bit more and get the real deal.
I haven't looked into it that much just yet to be honest, I'm concentrating on sorting out a brake upgrade and a few other bits first!
