On a recent episode of the Carmudgeon Show podcast, auto journalist
Jason Cammisa described a phenomenon occurring with some LED headlights
in which there are observable minor spots of dimness among an otherwise
bright field of light. “With complex arrays of LEDs and of optics,” he
said, “car companies realized they can engineer in a dark spot where
it’s being measured, but the rest of the field is vastly over-illuminated.
And I’ve had now two car companies’ engineers, when I played stupid and
said, ‘What’s the dark spot?’ … And the lighting engineers are all fucking
proud of themselves: ‘That’s where they measure the fucking thing!’
And I’m like, ‘You assholes, you’re the reason that every fucking new
car is blinding the shit out of everyone.’”
I'm glad I'm not the only one who has been noticing this. The piercing white of high mounted LEDs lately makes driving at night very difficult, and there have been times when I literally cannot see the side of the road next to me from the oncoming vehicles.
My compromise has been to up the lighting on my motorcycle so I stand a chance of seeing the road edge and what's beyond it, but I really don't like having to do so.
It's at the point where I can see the shadow of my car at night when one of these vehicles is behind me. Bright white light along the road to both of my sides and a giant ass shadow that makes it seem like I don't even have my lights on.
it's terrible, I often have to drive one handed for a short time while I hold up my other hand to block the light from whatever direction its source is. Sometimes this means shielding the side view mirrors which also get intensely bright from the reflection.
