I know the luxury package includes Xenons, which I like a lot. They're super bright. I can barely imagine anything better, but the Adaptive Xenons sound great.
I have the adaptive HIDs in my current LR4. To be quite honest, I'm a little disappointed with the small mount of movement (side to side when turning) they have. I have had previous vehicles with adaptive headlights which were much more "adaptive" than the ones in the LR4.
