Yeah, but it's a pretty pathetic passtime. At least find a good reason, rather than doing literally the thing you want them to do.
Like, insulting them for leaving is just as bad as them crying that their toxic behavior scares people away. It makes no sense.
The problem isn't LEDs though. The technology isn't what's making it bright.
The regulation needs to be specific about what they want the end result to be, not about the specific technology used.
Like: there should be a mode of operation where oncoming traffic at x distance, seated at y height, on level roads should not experience more than z brightness.
