Methods and systems for providing advance warning of a change in status of a traffic light to drivers approaching an intersection. The systems and methods include secondary lights positioned in advance of a traffic light at an intersection so that they are visible to oncoming traffic; and using a controller to control the plurality of secondary lights to start flashing before the traffic light changes from green to yellow. Once activated, the lights flash in the direction of oncoming traffic to warn drivers approaching the intersection that a stop may be required and that caution should be exercised.
