Some details on the requirements: > Some of the differences in testing between [international standard SAE] J3069 and the final rule adopted by NHTSA include applying the glare limits at all ranges as opposed to at specific points (30 meters, 60 meters, etc.) in the SAE test. The final rule also specifies actual curves of various sizes as opposed to using simulated curves as well as using actual vehicles instead of assemblies intended to simulate vehicle lamps. NHTSA defended its choice noting that many of the tests are the same. > "The final rule follows SAE J3069 in many significant respects but is different in some areas due to safety considerations. For example, the SAE standard permits up to 25% increase in glare compared to current limits and would allow systems that do not provide benefits beyond standard lower beams to be marketed to consumers as AFS," said a NHTSA spokesperson. https://www.newsweek.com/nhtsa-roadblocking-headlight-technology-that-could-save-lives-1811354 https://www.newsweek.com/nhtsa-roadblocking-headlight-techno...
