Add on (i.e. aftermarket) LED lights are a problem. They are rarely aimed correctly and the glare is blinding. I have been known to wear my sunglasses at night to try and preserve my night vision. And sometimes factory LED lights are not much better. I had a Rivian behind me (way behind) on the highway and its lights were crazy bright... I had to move my mirrors. Police car emergency lights are even worse, I think they might actually be bright enough to cause damage.
I usually flash my high beams at drivers with bad LED's, but I don't know that they "get it".
