Wait, are you saying aftermarket LEDs are road legal in US, no strings attached?
Throughout Europe it's either straight prohibited to retrofit LEDs in place of halogen bulbs, or it requires special certification where beam patterns are checked.

The policy is probably the de facto assumption that driving is a right: the United States has been rebuilt around the need to drive everywhere and the entire system tends to implicitly assume that anything which would impede someone from driving is unconscionable unless you get to the point of a serious collision or fatality.
The vast majority of states don't even have safety inspections, and some have recently discontinued them.
They take away driver licenses all the time in the US though. DUIs being the most notable, but even getting enough tickets can result in losing your license, or having it suspended. I know at least a dozen people who lost their license at some point.
That's why it is penalized by driving license cancellation in some countries. And people do get stopped for too bright headlights, because it's so easy to notice and check.
Sadly this is not the case with headlights and most of things in the US… unless youre a minority, then you cant even walk down the street without being worried.
