Calling the Soft Lights Foundation an "organization" would be generous: it's largely being held up through the goodwill of one man, Mark Baker. Baker, the founder of the SLF, is an Oregonian (although he claimed to now be living in California in a court filing earlier this month) with autism who, as it eventually turned out, acquired PTSD from being exposed to LEDs and now cannot handle them to any degree.
The SLF presumably got its name because, when it started before COVID-19, it focused on LED lights being too cool. At some point in the summer of 2022, Baker worked out that his issue with LEDs was not that they were emitting white rather than yellow light, but that they instead emitted light from flat surfaces and were therefore extraordinarily bright. Around that time, he decided to flood almost every federal regulatory authority that looked like it had competency for LED regulation to create such regulations.
Baker has submitted letters to an Assembly member in California, a Congressman in Michigan and multiple statewide emergency vehicle regulatory authorities, but appears to have only taken three actions in Oregon: one ADA lawsuit of his own, assistance in another ADA suit, and a letter about emergency vehicle lights that predates his more recent wave. I am honestly surprised he has not gotten one of his associates in Washington state to draft and circulate an Initiative to the Legislature.
