I've been considering a set of the lights mentioned in this thread
http://www.zpost.com/forums/showthre...ghlight=spyder
There are HID
and
non-HID versions
( HID = high intensity discharge for anyone like who needed their memory refreshed)
From what I can gather the E85 Z4 could come with HID or non-HID headlights from the factory? If so what was the determining factor? Did just the Z4M have HID headlighs? Was it part of the face lift in the later years? A factory option?
I am also getting the impression that if you have non-HID lights you can't simply blot on a set of HID lights correct? And I'm under the impression that its due to more than just a different physical plug for each headlight.
I'm fairly confident that my 2003 Z4 3.0i has non-HID lights but I am basing that mostly on the fact that they don't seem to provide much light.
Can I tell for sure based on year or by inspection?
Just wanted to make sure I am understanding correctly before spending the money, and I hadn't seen it covered specifically in the other threads I've read.
