You can retrofit LEDs and HIDs, but you have to do it with the correct projectors. Then there’s a proper cutoff and you even get more useful light output. But you should still only do this with self-leveling headlights already installed in the car and in the EU you’d need headlight washers as well.
That seems like mostly an issue with aftermarket headlights, at least in my area
LED replacement bulbs for cars are bad and you shouldn’t use them.
