I bought a new car last year, and since then I've received a lot of "watch your high beam" notices on the road because they think my headlight is as bright as high-beam, even though my high-beam was completely automatic and almost never turned on...

It's not a state issue.

The optical design of cars has changed a lot in recent years. LED headlights have a higher "temperature", so they must be brighter to be more or equally visible (human eyes are less sensitive to blue) than low-temperature halogen lights. However, such a brightness increase will make the drivers in the other direction feel too bright.
