I have just installed the 23 LED ones today. Absolute biatch of a job too - but that is entirely due to not being able to get the original bulbs out; the cover had virtually sealed itself shut. Mine needed a little sanding and the prong ports widening (easy with a scalpel blade); but once I had done one the other side went much quicker. I didnt take my wheels off but found that turning the wheel outwards gave me better access than inwards.
They are definitely not as bright as stock fried egg bulbs but there is not that much in it.
I got mine from the same eBay vendor as Chris; he is called 909_BMW. I ordered the 18LED ones but he sent me 23LED ones free of any extra charge because he ran out if stock. Good prices and a good seller I would say. No flicker that I have noticed either.
