Have you any advice on adjusting headlights for the amateur? This explanation is hard for me to follow. I usually drive out to a flat country road in the dark and adjust by eye.

Before headlights became part of the body lines, New York State required properly adjusted headlights as part of the yearly vehicle inspection. We had alignment devices that suctioned onto the sealed beam headlights. A few moments with a phillips head screwdriver and you were done. I think a lot of the blinding brightness today is due more to improper adjustment than the brighter bulbs. Headlight alignment checks should be an inspection requirement again.

Keep in mind the after market LEDs may not generate enough heat to prevent ice from forming on those head lights

I always curse you guys running hid or led in a reflector style headlights. Very unfriendly move towards your fellow drivers. I don't flash, not worth getting in a headlight pissing contest.
Check a scrapper for the factory projection headlight assembly if you want to join the hid / led club. Alternately retrofit projector lenses can be had for most trucks.
Actually it is not HIDs or LEDs in THOSE folks lights..
Sorry, but you're wrong. I can spot HID/LED retrofits in a halogen reflector housing quite consistently. The weird hot spots and scattered light are a dead giveaway. Although the blue tinted halogens are annoying, cheap HID/LED retrofits are worse.

Daniel Stern is an expert on automotive lighting, and he has written this about conversion bulbs for turning halogen (xenon) headlights into HID headlights. Nearly all of the basic concerns are the same for LED conversion bulbs, despite the technical differences between HID and LED (and incandescent) lights.

I put LEDs in my 2013 CRV. They are great! No adjustment required. They put the hot spot on the road about 30 feet in front of the car.
They do not shine in the rear view mirror of the car in front of me. I went to a large commercial garage door at night to see the pattern. No out of place stray light.

A hot spot on the road 30 feet in front of the vehicle is not good. That tends to focus your attention there, much too close to be able to react to anything except at very slow speeds. That also makes the pupils in the eyes close a little and so reduces distance vision.
Having lots of light near the vehicle does make the lights look nice and bright and effective to the driver. It's an unfortunate irony that this is misleading and they are not actually as effective. (There does need to be some balance in things, of course. One doesn't need or want a black hole in front of the vehicle. Even illumination, perhaps with a bias towards farther distances, is ideal--with a good cutoff for the low beams.)
Installing bulbs other than the type specified makes the headlights no longer DOT approved and therefore at least technically illegal, for what it's worth. Unless egregiously bad I suspect you're not too likely to be fined or otherwise harassed.
OK, then tell us where the hot spot should be for low beam head lights. I'm sure you are a qualified/trained expert in the automotive lighting business. If you feel the need to condemn, then offer the documented correct answer.
And you might want to read this.
