hey guys,
I'm thinking of upgrading to angeleye. But I was wondering, if there is any difference between regular head lights, and stock angeleye. I know a guy who sells them. But I thought I would need some sort of a voltage converter for HID, but he is not selling them. Would I need those? Is the fitment of plugs going to be the problem? After the install, would it move(bug eye affect) like the stock? It souldn't be a problem with ECU right?

Sorry for newbee questions, but it is my first bimmer, and it is very different than japanese cars.
