Same form factor doesn't mean same reflectors. It just needs to fit into the same space. You can fit LEDs into that space.
You could, but capitalism … most cars do not get aftermarket reflectors, no one would pay the significant cost, and LEDs fit into standard reflectors. There’s a whole bunch of failure here
We're talking about the sealed headlights with the reflectors contained in them. LED versions have their own reflectors that could be (and I assume are) tuned to work correctly with LEDs.
I don’t think I’ve seen those since before my teenagers were born.
A few weeks ago I showed my younger kid how to replace headlights on his old car
The problem is you can find led replacements that fit the same base “for offroad use”
When to be legal, to not cause glare problems, someone would need to re-engineer the assembly and people would need to be willing to spend that kind of money
