The AC noise is more of a ticking on mine.
If you’ll excuse the pun, the headlights are one of the few highlights on my car.
Great on dip, fine on main.
The auto function is a mess though, pleases itself.
Doesn’t dip when it should and nearly got me into a road rage argument the other night when it went onto full beam right behind a car on a dual carriageway.
I manually dipped it quick, but I could see the driver in front gesticulating, he quite rightly must have been wondering WTF.
I’ve not reported it as a fault, what’s the point.
