I have not investigated the automotive side, but I do know that the halogen replacement LED for motorcycles do not produce a good beam. They throw out light that is glare to oncoming drivers. The pictures that I saw on this thread, do not have the sharp line either. Some rules make sense are enhance safety. DOT rules for headlight makes sense. I replaced the entire headlight to obtain a proper beam.
Unfocused beams do not help you or others. I have experimented with 10 different brand motorcycle halogen replacement LED bulbs. Priced from $40-$200, none reproduced the beam pattern of the halogen. LED and reflectors do not work well for most bulbs on the market.
