The angel eyes come to the fog lights from the front, but I needed to move the fog-lights back a little bit. Not easy, as the nut is on a long bold, i.e. I would have needed a long socket, but there is no space for a long socket - luckily I had a half-long 10mm socket. I attached the angel eyes the low tech way: With silicone. Sounds rough, but this is not noticeable. I wiped off the excess in time and I though of something to press the angel-eyes into position, while the silicone dries.
