So PRE 2008 headlights (meaning the entire clear plastic shroud and electrical assembly) don't have the upper array of illumination. They just have reflector looking materials in that upper area.

2008~2010 they were revised.

Does anyone know

1)Can a 2007 use those as is? Must an an entire system upgrade be performed? Will it fit with stock body parts?
2)If it can be done, does anyone know a good source for retrofit kits or can I simply just buy a pair of 2008~2010 headlight assemblies and be done?

Thanks in advance!

The car in question is a 2007 E64 M6 convertible.
The upgrade/retrofit in question would be the 2008 up to 2010 exact same model.

I checked bimmer tech but they are strictly interior and sound.

The idrive CIC Nav retrofit is absolutely incredible
