(OPINION!) LED Replacement Headlamp Bulbs

Automakers must PROVE that their headlight designs will pass all Federal regulations concerning headlight glare.

I'm wondering if this is really true and/or enforced. Even in cars with factory LEDs, I'm often hit with near-blinding light when close to passing them in the opposite direction. They're throwing out light above eye level at 80 degree or so angles. And sometimes when one is behind me, the inside of my car becomes brightly lit. Some of the factory LEDs are pretty much as bad, glare-wise, as the LED retrofits in reflector housings. I'm of the opinion that an LED retrofit in a projector headlamp is ok, so far as blinding other drivers goes.
