sometimes its the three blind men describing the elephant from different sides. I get some folks like stock, other mods, or electric. In this case, original lights, halogen, LED.
There can be more than one solution to a problem.
First, your expectations for what constitutes good lighting can differ significantly from others. Therefore what solution meets your needs can be ifferent than what meets mine. So getting multiple opinions is, imho, a good thing.
Second, I believe good solutions have been reported for many of these different approaches (all but 1).
Third: therefore I think it incorrect to characterize multiple good solutions as blind men misidentifying the whole issue. It’s more like 3 blind men arguing about what’s the right amount of water to put into a good scotch whiskey.
Fourth, some folks prefer not to wade their data, and want a simple-definitive, “this is the one truth so just do this one thing.”
IMHO you’ve already received enough advice to have at least 3 good solutions. FWIW, I’ve never regretted following HBChris’ advice. If you agree you could stop reading here and go buy something ...
But if you are an information addict (I am), here is more opinion to complicate matters
I’ve used these
(1) commonly avail flat face Hella’s,
https://www.rallylights.com/hella-5-3-4-round-ece-high-low-beam-headlamp-no-bulb-hl79564.html. AFAIK, the overall design of these has not changed in decades. When they get cloudy (film on the inside of the lens, they can be cleaned but avoid harsh chemicals as theinternal silvering is not robust like paint. Acetone will take the silvering off but windex seems ok.
(2) the NLA Hella bifocus low beams with #1 high beams.
(3) Cibies (non CSR), from the mid 1980’s, which look like what Daniel Stern sells. I remember then these were under $20.
(4) USA DOT sealed beams.
Of these 4, only the DOT sealed beam #4 provided less than acceptable night lighting for my aging eyes. #2 was the best but I’ve remove the bifocus because of their rarity and I didn’t feel I needed their extra performance. None of these are as good in uniformity as the best headlights I’ve used (bi-Xenon on BMW E60 and single Xenon on Mercedes W166). YMMV.
LED: I’ve seen a few LEDs in incandescent housings. Some were horrible and some were almost as good as the aforementioned 3 good ECE solutions. The good ones were very bright but had only modest uniformity. I hate lights that put too much light close to the car because it hurts your ability to see into areas further away. I subscribe to the notion that you shouldn’t over drive your vision so more light further out is far more important to me that perceived overall brightness of the entire visual field.
I don’t feel the any of the hybrid LED bulbs in incandescent housings would improve on the Euro halogens in any of my old cars. But, I have a friend (RIP), who retrofitted the complete OEM 7” LED assembly from a modern car into a 1960’a car, and those worked very well (eg not just a bulb change).
