From RealOEM your 3.0Si roadster has xenon headlamps as the outer projectors. And as you stated, the inner "projectors" are dummies with only the halo running lamps. I have the same setup on my 2006 3.0Si coupe.
If you are new to owning a BMW, you may not have yet bookmarked RealOEM, and you will find it here:

Choose your car by VIN, and save the URL for reference. Prices are usually out of date, but part numbers are very useful - even though you might need help from this forum in finding your part within RealOEM
