Greetings. I'm new to the BMW market, so please forgive my ignorance. I see BMW's advertised with so called "Angel Eyes" and "Xenons". Are these terms used to describe the same technology?
Many thanks.

No.
Xenons and Bi-Xenons are headlights comprised of High Intensity Discharge (HID) light sources. Xenon equiped cars use the Xenon lights as the main driving lights but still use old style halogen bulbs for the brights and flash-to-pass. Bi-Xenon equiped cars use the Xenon lights for both normal driving lights and the brights and the flash-to-pass is still done with halogens. (You want a light that comes to full brightness very quickly for the flash-to-pass functionality. Halogen bulbs come to full brightness very quickly whereas xenon bulbs take a lot longer. In the case of Bi-Xenons, there is a louver that partially obstructs the bulb when in normal mode and which retracts for the brights. The louver takes longer to retract than the halogen bulbs come to full brightness)
This is a Xenon headlight:
Angel Eyes (also called Demon Eyes) are rings of fiber optic material that surround the headlights. When turned on they provide a glowing ring around the headlights, which is more easily seen when the headlights are not on. In most cases the angel eyes rings use a set of small halogen bulbs (like those found in the small halogen desk lamps) whose light is fed to the rings via fiber optic cables. New angel eyes also use high intensity LEDs as a light source as the LEDs can be fitted at the ends of each ring so are simpler than he halogen/fiber types.

I just noticed that the picture with the Xenon headlight also has an angel eye ring on it.

I don't have HID but you can't tell without the Xenon being on. I agree though, it's odd without the projector lens.
