In 2008 the US Department of Transportation, National Highway Traffic Safety Administration (NHTSA) assessed the risks associated with glare, as directed by the US Congress.
Softlights.org, an organization “dedicated to safe, responsible, human compatible outdoor and vehicle lighting,” has noticed that the above report was the last time the issue of glare was assessed at this level. Now they are campaigning for a re-evaluation – which is reasonable, given that LEDs, lasers, and other technological developments are now widespread even though they were not yet prevalent in 2008.
