It depends. Traffic lights are just mutexes. They are there to stop traffic so that other traffic may pass safely. There's no point if there aren't any other cars. Obviously anyone running a light on a busy intersection deserves to get fined but if you know the terrain, have good visibility into the road where the other traffic comes from and can clearly see there are no vehicles present, running the red light is utterly harmless.

In my city, certain traffic lights literally turn off at night. There's not enough traffic flowing to justify them.
