You made me remember of a period around 2012 when, due to my country being under external financial supervision, most cities and town opted to disconnect street lights to save on the energy bill.

Turns out that anywhere between 35% and 60% of all street lights are superfluous, there was no increase in insecurity and close to nobody felt the need to supplement the light outside with their own.

In my own little town, nights became quieter. Foxes, owls and other night dwellers could be seen roaming.

People complained but when met with no other option adapted and adapted fast and well. Many street ligths, previously using sodium lamps, were changed to LED, allowing for many lamps to be removed.

I would personally like to have less lamps in the streets and those with lower intensity. It could be done. This isn't London anymore.
