I have a call into my dealership with the same question. I have the comp model & out of the box it has the standard turn signals vs the leds. They were going to look through the box today, to see if they came with it.
Last thing I read was greggs customs is making flush mount LEDs. I also heard Watson designs will start making them again and supporting the 2012/13 fairings starting sometime in January. A forum vendor also makes some pretty sweet led backlit bmw badges that you could use. His member name is something 360.
I went to my dealer today and saw my HP4 and noticed the regular bulbs on it too. He told me the euro specs come with LEDs and the American specs come with regular bulbs. All the ones you have seen on the internet were euro spec according to him.
