Abstract

This disclosure relates to a lighting system for a rear of a motor vehicle and a corresponding method. In particular, an example lighting system includes a first rear combination lamp and a second rear combination lamp, the first and second rear combination lamps each including a first lighting section configured to illuminate a first color and a second lighting section configured to illuminate one of an second color and a third color. The system further includes a controller configured to selectively illuminate each of the first and second lighting sections.

Claims

1. A lighting system for a motor vehicle, comprising:

a first rear combination lamp and a second rear combination lamp each including a first lighting section configured to selectively illuminate a first color and a second lighting section including multi-colored light emitting diodes (LEDs) configured to selectively illuminate the second lighting section one of a second color and a third color; and

a controller configured to selectively illuminate each of the first and second lighting sections.

2. The lighting system as recited in claim 1, wherein:

the first color is a red color,

the second color is an amber color, and

the third color is a white color.

3. The lighting system as recited in claim 2, wherein:

each of the first lighting sections includes a plurality of red LEDs configured to selectively emit light of a red color; and

the multi-colored LEDs of the second lighting sections are bi-color LEDs configured to selectively emit light of either an amber color or a white color.

4. The lighting system as recited in claim 1, wherein each of the first and second rear combination lamps consist of only two lighting sections.

5. The lighting system as recited in claim 1, wherein the controller is configured to selectively illuminate the first lighting sections of the first and second rear combination lamps to indicate a braking operation.

6. The lighting system as recited in claim 5, wherein, during a hazard flashers operation, the controller is configured to selectively illuminate the second lighting sections of the first and second rear combination lamps in the second color.

7. The lighting system as recited in claim 5, wherein, when the motor vehicle is in a gear other than reverse, the controller is configured to selectively illuminate the second lighting sections of the first and second rear combination lamps in the second color to indicate a turn signal.

8. The lighting system as recited in claim 5, wherein, when the motor vehicle is in a reverse gear, the controller is configured to selectively illuminate the second lighting sections of the first and second rear combination lamps in the third color.

9. The lighting system as recited in claim 5, wherein, at all times when the motor vehicle is in a reverse gear, the controller is configured to selectively illuminate at least one of the second lighting sections such that a white light is emitted from the motor vehicle.

10. The lighting system as recited in claim 9, wherein, when the motor vehicle is in a reverse gear and during a hazard flashers operation, the controller is configured to periodically alternate between illuminating the second lighting section of the first rear combination lamp in one of the second and third colors and illuminating the second lighting section of the second rear combination lamp in the other of the second and third colors.

11. The lighting system as recited in claim 9, wherein, when the motor vehicle is in a reverse gear while a turn signal is activated, the controller is configured to periodically illuminate the second lighting section of one of the first and second rear combination lamps in the second color to indicate a turn signal and to illuminate the second lighting section of the other of the first and second rear combination lamps in a white color to indicate the motor vehicle is in a reverse gear.

12. The lighting system as recited in claim 1, wherein the first rear combination lamp is adjacent a right side of the vehicle and the second rear combination lamp is positioned adjacent a left side of the vehicle.

13. A method, comprising:

selectively illuminating a rear lighting system of a motor vehicle, the rear lighting system including a first rear combination lamp and a second rear combination lamp, the first and second rear combination lamps each including a first lighting section configured to illuminate a first color and a second lighting section including multi-colored light emitting diodes (LEDs) configured to illuminate the second lighting section one of an second color and a third color.

14. The method as recited in claim 13, further comprising:

illuminating the first lighting sections of the first and second rear combination lamps to indicate a braking operation.

15. The method as recited in claim 13, further comprising:

illuminating the second lighting sections of the first and second rear combination lamps in the second color during a hazard flashers operation.

16. The method as recited in claim 13, further comprising:

illuminating the second lighting sections of the first and second rear combination lamps in the second color to indicate a turn signal when the motor vehicle is in a gear other than reverse; and

illuminating the second lighting sections of the first and second rear combination lamps in the third color when the motor vehicle is in a reverse gear.

17. The method as recited in claim 13, further comprising:

illuminating at least one of the second lighting sections such that a white light is emitted from the motor vehicle at all times when the motor vehicle is in a reverse gear.

18. The method as recited in claim 17, further comprising:

periodically alternating between illuminating the second lighting section of the first rear combination lamp in one of the second and third colors and illuminating the second lighting section of the second rear combination lamp in the other of the second and third colors when the motor vehicle is in a reverse gear during a hazard flashers operation.

19. The method as recited in claim 17, further comprising:

periodically illuminating the second lighting section of one of the first and second rear combination lamps in the second color to indicate a turn signal and illuminating the second lighting section of the other of the first and second rear combination lamps in a white color when the motor vehicle is in a reverse gear while a turn signal is activated.

20. The method as recited in claim 13, wherein

the first color is a red color,

the second color is an amber color, and

the third color is a white color.
