Most if not all "kits" are not complete. The requirement for HID's to work effectively, involves projector lenses (which are required to focus the light correctly, A self levelling system (because of the way the light is focused) and a headlight washer system, also because of the latter.
Your car will have none of the above. Also note that the law has recently changed in an attempt to be more clear on the facts as it has been a grey area for years.
It doesn't matter that other people have them, it doesn't matter that the local plod don't care, it doesn't matter that you are friendly with a local MOT tester who will pass them. Incorrect fitment is a nuisance to other road users and in mine, and many others opinion are deemed dangerous.
I hope you get round to changing them soon.
