>> Do they have some sort of internet capability, maybe a SIM card? I assumed they were controlled by a photocell
LED streetlights were installed in our cul-de-sac and on the approach road in the Spring. They are definitely connected online in some way, as they all (around 20) turn on simultaneously at dusk and all turn off together on the stroke of midnight (to the second, as per my radio-synced alarm clock). For some reason they stay on until 01:00 on a Friday night but not on a Saturday.
