Fair enough, I wasn't sure (though I could have looked at my spare lamp set).

I don't understand it either. The reduction in dazzle would be a
considerable help to see things that are more important than other brightly
lit vehicles.

For instance, it is remarkable how far away pedestrians dressed in black can
be seen under steet lighting when there are no oncoming lights. Or two
drivers negotiating parked cars would be able to judge road widths and
distances better.

I usually stick with headlamps because it has become an unfortunate part of
our motoring culture. But unless I need a patch of light cast along the road
I always use the dashboard knob to set lowest elevation.

I am probably one. But I give the opinion as a driver. It's one thing having
lights that are good enough to show up, but it's ridiculous that they are so
bright they mask whatever is beyond.

Nor am I.

I thought it was dumb. What's wrong with dipped headlights?
