I tried pointing out to the local lighting officer and my County Councillor that lower colour temperature LEDs were better, as they reduced scattered light in hazy/foggy conditions
You would probably have more success going on social media saying blue LED lighting causes cancer. (Unlike with 5G there is apparently some evidence to support this and has caused some towns in the US to rip out their recently installed blue LEDs in favour of lower temperature versions. See a presentation on this at the 2018 joint BAA/AAVSO meeeting). Failing this, pointing out the effect on wildlife might gain more traction among the general public, particularly if yo have any green councillors
