They certainly look like the angels on offer, with the eyebrow above.

patriot66 said:The lights in your photos look like 2Xcite/Sonar lights. Look for the brand name moulded into the clear cover in the lower inner corner of each unit.
I have fitted 2Xcite lights on my Z4.
The quality may not quite be OEM but they are fine. Mine don't leak or suffer from condensation. I fitted Osram Nightbreaker bulbs and they give good illumination in dip and main beam. I drive home from work in the dark every night and I haven't hit anything yet ! I also fitted Osram Diadem Mirror-finish indicator bulbs which flash super bright orange and Osram Blue sidelight bulbs which make the 'eyebrow' look whiter than in the photo. The Halos are not as bright as current BMW OEM Halos or DRLs but are clearly visible in all but bright sunlight. My own experience of 2Xcite lights has so far been good.
The ones in your photo look as if they may have been fitted for some time judging by the surface rust on the adjuster nuts. You need to investigate how the Halos, 'eyebrows' and central LEDS have been wired up to the existing wiring to give you an idea why they don't work.
If you can get them working and also fit better bulbs I think you will be much happier and it won't cost you much either.
