Abstract

A wireless taillight system is provided having a taillight module (150) removably mountable on a vehicle such as a wagon (125) being pulled by a farm tractor (100). Module (150) has at least one signal lamp illuminable by a wireless control signal transmitter module (200) having a power source carried thereby that along with module (150) is preferably operable to transmit a feed-back signal to transmitter module (200) to provide the operator with information concerning one or more of: (i) the condition of the signal lamp; (ii) the condition of the power source powering the signal lamp and; (iii) whether a function selected by an operator has in fact occurred.

Claims

1. A wireless taillight system comprising:

a taillight module adapted to be removably mounted on a vehicle, said taillight module including at least one signal lamp selectively illuminable by an electrical power source to provide visual information concerning a particular condition of the vehicle and said taillight module including means for receiving a transmitted wireless control signal and for enabling the power source to illuminate the signal lamp upon receipt thereof;

a portable transmitter module powered by a power source carried thereby independent from the vehicle, said transmitter module selectively operable by an operator to transmit the wireless control signal to the taillight module;

said taillight module including means for transmitting a wireless feedback signal concerning one or more of;

a condition of the taillight module signal lamp;

a condition of the power source; and

whether a function selected by the operator has occurred; and

said transmitter module including means for receiving the feed-back signal and for providing information to the operator derived therefrom.

2. The taillight system of claim 1 wherein the taillight module signal lamp condition is a failure of the signal lamp to illuminate and the power source condition is a power level below a predetermined value.

3. The taillight system of claim 1 wherein the taillight module further includes a message illuminable by impinging light or upon receipt of a selected transmitted wireless control signal and the transmitter module includes means for selectively transmitting said control signal.

4. The taillight system of claim 1 wherein the feed-back signal is a radio frequency feed-back signal.

5. The taillight system of claim 1 wherein the feed-back signal is a selected one of a sonic signal, an ultra-sonic signal, a laser signal, and an infra-red signal.

6. The taillight system of claim 1 wherein the transmitter module has a selectable "off" and "on"condition and includes means for providing a visual signal when said module is in the "on" condition.

7. The taillight system of claim 1 wherein the transmitter module has a selectable "off" and "on"condition and includes means for providing an audible signal for a predetermined period of time when said module is in the "on" condition.

8. The taillight system of claim 1 wherein the transmitter module includes means for providing a visual signal upon activation of a selected function.

9. The taillight system of claim 1 wherein the transmitter module includes means for providing an audible signal for a predetermined period of time upon activation of a selected function.

10. The taillight system of claim 1 wherein the transmitted wireless control signal is an intermittent control signal.

11. The taillight system of claim 1 wherein the transmitter module includes means for providing a visual signal when the taillight module signal lamp fails to illuminate upon receipt of the selected control signal.

12. The taillight system of claim 3 wherein the transmitter module includes means for providing a visual signal when the message fails to illuminate upon receipt of the selected control signal.

13. The taillight system of claim 1 wherein the taillight module includes means for monitoring an absence time period for control signals received from the transmitter module and further includes means for turning off the signal lamp when the absence time period exceeds a predetermined value.

18. The taillight system of claims 1, 14 or 15 wherein the taillight module includes a motion sensor operative to shut off the taillight module power source in the event the taillight module remains motionless for a predetermined period of time.

14. A wireless taillight system comprising:

a taillight module adapted to be removably mounted on a vehicle, said taillight module including at least one signal lamp selectively illuminable by an electrical power source to provide visual information concerning a particular condition of the vehicle, said taillight module including means for receiving a transmitted wireless control signal and for enabling the power source to illuminate the signal lamp upon receipt thereof, and said taillight module including means for transmitting a wireless feed-back signal concerning one or more of;

a condition of the signal lamp;

a condition of the power source; and

whether a selected function has ocurred; and

a portable transmitter module powered by a power source carried thereby independent from the vehicle, said transmitter module selectively operable by an operator to transmit the wireless control signal to the taillight module, and said transmitter module including means for receiving the feed-back signal and for providing information to the operator concerning the condition of the signal lamp, the condition of the power source, and whether the selected function has been activated.

16. The taillight system of claim 14 or 15 wherein the taillight module further includes a message illuminable by impinging light or by the power source upon receipt of a selected wireless control signal and the transmitter module is operative to selectively provide said control signal.

17. The taillight system of claims 14 or 15 wherein the feedback signal is an intermittant signal.

15. A wireless taillight system comprising:

a taillight module adapted to be removably mounted on a vehicle, said taillight module including;

a left turn signal lamp and a right signal lamp respectively disposed near opposite ends of the module,

an additional signal lamp disposed adjacent the right turn signal lamp and an additional signal lamp disposed adjacent the left turn signal lamp,

said signal lamps selectively illuminable singularly or in predetermined combinations by an electrical power source to provide visual information concerning a condition of the vehicle,

said taillight module including means for receiving a transmitted wireless control signal and for enabling the power source to illuminate the signal lamps upon receipt thereof,

said taillight module including means for transmitting a wireless feed-back signal concerning a condition of the signal lamps;

a condition of the power source; and

whether the selected function has been activated,

a portable transmitter module powered by a power source carried thereby independent from the vehicle, said transmitter module selectively operable by an operator to transmit the wireless control signal to the taillight module,

and said transmitter module including means for receiving the feed-back signal from the taillight module and for providing information concerning the condition of the signal lamps, the condition of the power source, and whether the selected function has occurred.
