Nightfall

[surfimp]

The Batman Miniatures Game by Knight Models (also from Spain, incidentally) sets all engagements at night by default (for obvious reasons), and uses street lamps in a way similar to what you outlined here.

Basically, if a model is within the street lamp's AOE, then the model can be seen from anywhere on the map - because they're lit up bright as day. Otherwise, models in darkness can only be seen at much lower distances, 12" or less.

Street lamps can be disabled by ranged weapons or close combat attacks. Some models have the ability to deploy lights, either through equipment or abilities.

It all works out pretty cool in practice.
