I've never owned a car with HID lights so I don't know if all HIDs are like this. I'm having a very difficult time seeing at night with the low beams because there is such an abrupt cutoff line. I feel like I can't see anything beyond the cutoff line and that line doesn't extend out far enough for me to comfortably know what's ahead.
Is this something that just takes time getting used to or is there an issue with V60?

 

The headlights mirror is quite weird on the S60.. that said, sometimes garages will not install correctly the bulbs because it doesn't easily fit in there and there's also a retaining clip. Also, old bulbs will became dimmer. Finally, on my car I also had a very difficult time seeing ahead at night. The light beam was pointing quite downward and the trow distance was limited. It's easy to adjust upwards a little bit the light beam, just make sure it's within the law.
