About 30 years ago, i started to use aftermarket halogen headlights on my car (back when 7 inch round headlights were the norm). I believe the brand was cibie. Those headlights were not approved for usein the US because they were not a sealed beam.
While there were a few police officers who took the time to inform me that they disapproved of the speed at which I was driving, the illegal headlights were never cited. The car even passed state inspections.
The point here is one of degree and risk, and what of the former the aftermarket lightbulb presents of the latter. The rest of your messages I read as more specious posturing than anything else.
