Anyone else notice that many active LED headlights are really inactive? - Page 3

To me, the high beam works reasonable well (though lacking the high tech features apparently available in other countries). However, when the auto system switches to low beam it feels downright dangerous! There is a very definite threshold between illuminated and dark areas when in low beam. I.E. the road is illuminated for a reasonable distance in front of the car but essentially dark above that. For example, at times we could easily see the tires and bumper of a car ahead but barely see the back window. Last night as we drove out our dark, hilly, lane we barely notice the feet of deer along side the road. We were going down hill and the deer was standing along side maybe a couple of feet higher than the road. As we were coming home a car approaching ours blinked its lights OFF. I assume the driver thought we didn't have ours on.

Here are a couple of pictures taken this evening. First one is low beam on, second is high beam from same location.

Low Beam

Notice that in the low beam image there's not a hint of the tree on the right side of the road, or the brush sticking out on the left at about the same distance.
Seems like, rather than dimming the light on low beam, the vehicle is concentrating it in a small area - leaving other critical areas dark.

The manual included in the MBUX system (under INDEX) has an animation showing what I had hoped for. Nothing like what I got.

Has anyone else noticed this?

The upper lights are shut off on low beam. If you pull up to a garage door or wall you will see it more clearly. There is a straight line at the top like someone covered the upper light. Since the active headlights aren’t operative in the US it appears they just deactivate all the uppers to act like the lights dim to avoid blinding oncoming traffic.
