The brow and angel eyes dim when the headlights are on. But I assure you they are on. There is a way to code for them to stay full brightness while the headlights are on, but I haven't done it.
This will work in any F30 except the wiring and parts are different. I would say at least the headlight control modules will be different to take into account driving on the wrong side of the road ;p. Also, I know most euro spec cars have manual leveling functions. This results in different wiring in the harnesses. It actually makes it a little easier. Someone else was working on doing a retrofit for those, Aloo6,but not sure of his progress. If there is really a demand for it, I can maybe write up the difference one day if I ever get time, but I am hoping someone else does first
