We made LED lighting white because we wanted it. We can make yellow LED lighting as well. This should be suggested to city councils, if changing the wavelength would be beneficial to insects with no downsides.


I'd be so stoked for red street lights. They don't mess up your vision at night.


Indeed. Nor does red light mess as much with animal (incl. human) physiology and behaviour and waking cued by white/blue/daylight.

Potential small (safety?) downside: red light illumination does greatly reduce colour discrimination at night versus white light.


Belgium uses yellow light. And, unlike its neighbors, it has lights all along its interstates. Quite eerie to see when you’re not used to it.
