This is a new used car to us. The DRL daytime running light sensor on the dash flickers and buzzes when the car is put in drive. The sensor is disengaged when the headlights are turned on, so this dismisses the electrical buzz and flickering, but the right highbeam light will not work. The headlight on that side has been replaced TWICE and is still brand new. It's not the light... it's the system. So we have NO highbeam on the right no matter what we do. We see this exact issue described by another user in NB, the behavior and result is exactly the same. SO FRUSTRATING, it is a safety issue, as good vision at night isn't possible without high beams .... and this would be ticket after ticket driving with one headlight if we used highbeams, which we can't.
