I don't believe that you can determine which headlights are illegal by looking at oncoming traffic. I don't believe that dealers or or drivers are modifying them in illegal configurations at more than a minimal rate. This would be quite the conspiracy.

Anyone can. Headlights are collimated by reflectors. If the lights of oncoming traffic are in your eyes at a distance of half a mile or more, then it is obvious they are misaligned, as proper alignment necessarily requires they be at an angle pointed at the road no more than 150' in front of the front tires.

Conspiracy is not required. All that is required here is ignorance and/or entitlement.
