wherein the repeated cycle only include (turn time phase, green time phase, yellow time phase and red time phase);

wherein a red light cycle only include red time phase and a yellow light cycle only include yellow time phase.

8. The system for in-car traffic light of claim 1 wherein the owners of the vehicles can obtain the GPS database of the track points, the traffic light cycles database and maps in CD-ROM format and load them onto the vehicle unit or use microSD memory cards that are preloaded with database of track points and the traffic light cycles database.

10. The LED strip unit and the heads-up display unit of claim 1 comprise the same LED indicators and the intersection indicator of the LCD unit;

wherein the LED strip unit can be in a horizontal or vertical orientation;

wherein the intensity of the yellow or the red LED indicators increases when the vehicle is less than few meters away from a programmed intersection during yellow or red light phases;

wherein audio alert can be used to indicate when the vehicle is less than few meters away from a programmed intersection during yellow or red light phases.

12. Sun visors of vehicles made of transparent materials similar to Sunglasses to allow the drivers to have line-of-sight with the LCD or the heads-up-display of claim 1.

14. The system for emergency vehicle virtual preemption of claim 13 is integrating with the in-car traffic light system of claim 1 and comprising;

a long range transceiver as a component of the emergency vehicle unit to transmit preemption codes to all vehicles approaching intersections on the priority route of the emergency vehicle.
