But they have separate dip and main beam lights with a little indicator squashed in between them, not like the OEM lights that have a Bi-xenon outer light and a big indicator where the main beam light is on the fake ones.
The other issue with having to fit an HID conversion kit in them, is that the ballasts always take a while to reach full power. I used to have a kit in my Passat, but have recently swapped them for genuine Bi-xenons. They spark up straight away. Much better.
