LEDG vs Halogen Incandescent headlights

I have only limited experience with LEDs, and it's gonna stay that way.
IMO
they are retina burners to look at,
but have lousy penetration,
and even less ability to shine into a hole.
IMO
they make lousy worklights, lousy flashlights, and lousy lights in my home. I am slowly, as they burn out, converting my 40 or so, GU-10 potlights in my house back to halogen.
When I encounter LED headlights coming at me at night, I cringe. At age 68, my eyes are becoming slower to adjust, and so I am forced to drive by looking at the shoulder, and occasionally also have to slow down as the retina-burner passes by. This has been on-going for about 10 or so years, when they first became available.
There is no way I would put that on some other old-guy, so will never install LEDS on my car, cuz not every old-guy can drive by referencing the shoulder.
Furthermore, as regards LED tail-lights, like I said, LEDs have no penetration power. So in a snowstorm, it has happened to me that I have caught up to a vehicle with LEDS and nearly smashed into it. Whereas the non-LED cars gave more warning. My guess was that he was crawling along because his headlights also had no penetration power. I don't know that because I don't have and never will have LEDS.
Halogen headlights do what they are supposed to, without the retina-burning effect to oncoming vehicles. If there was only one thing in this world I could hate, it would be LED automotive lighting.
And that's my opinion.
