A method of providing an early warning system for vehicles approaching traffic lights (16) is disclosed that uses at least one transmitter (12), or transceiver, on the traffic light (16) and a receiver (14), or transceiver, in each of vehicle (18). The transmitters (12) transmit a signal at prior to the traffic light (16) changing color during a predetermined cycle, generally a single sequence of red, green, and amber light changes. The vehicles receiver (14) activates at least one alarm or indicator thereby notifying the driver of the action required. The transmitter (12) and receiver (14) can contain algorithms that control information transmitted and the response of the display panel. The vehicle transceiver can be connected to the on board computer system to receive and read data from the vehicle. When conditions, such as ice, prevent the vehicle from operating correctly, the algorithm transmits to the light receiver the need to delay the color change.
