With the release of update 2022.20, Green Traffic Light Chime no longer requires the FSD package.
It will require that you have FSD HW 3.0 and it will be available everywhere that Tesla supports traffic lights recognition.
As Tesla starts to support traffic lights in additional regions, this feature is also expected to arrive.
Once enabled, Green Traffic Light Chime will chime when a traffic light turns green.
The chime will sound a second after the light changes in case the driver is not paying attention. The chime will also sound when you are behind someone, once the vehicle advances.
The feature is disabled by default and will only work once enabled in Controls. The chime will also only occur when driving manually and not on Autopilot.
To enable the feature go to Controls > Autopilot and scroll all the way to the bottom until you see 'Green Traffic Light Chime.'
The ability for the car to chime when a traffic light turns green has been available for some time. However, previously the feature was only available to users with FSD.
Green Traffic Light Chime was first released almost two years ago in update 2020.36, but it was exclusively available to users with FSD.
It could be argued that the feature should have available to everyone from the very beginning, but it's a nice addition to those that do not have the FSD package.
Although the feature works well, it's worth noting that the chime should be used as an alert to check the traffic light, instead of as an alert to proceed.
In some cases the chime does go off incorrectly when it misreads a traffic light or doesn't understand the traffic pattern correctly.
