Everything else seems to work;
Auto Level (up/down) on start-up
Angel Eyes, etc.
Is there a way to troubleshoot what the failure point is? I'd drop it off at the dealership but the damn car is 2 months out of warranty. Of course. If I can figure out what's not working, I can certainly replace it myself.
Sadly, it seems that the headlights are replaced as an assembly. Others have had adaptive lights failures as a result of condensation, either by an improperly replaced cover, or by using aftermarket angel eye kits.
Here is another thread on the issue:
