Google has been toying with marking intersections with traffic lights for a few months now, but according to Android Police, the feature is getting a wide rollout.

Google Maps traffic light support is just a small, static marker in the middle of an intersection indicating that there is a traffic light there.

As always the map features are going to depend on Google's data set, and they are only seeing those in the US. They show up when browsing the map or navigating.

Google does not have a use for the traffic lights other than displaying them on a map, but it could end up with your navigation shout out "turn left at the next light" for verbal directions, one day.

Like many Google Maps features, traffic light data is enabled through Google servers, so there's no specific version of Google Maps we can point to that has it. If you do not have it yet you might get it one of these days.
