Vehicle and trailer lighting system

1. A vehicle and trailer lighting system, comprising:

an elongated track fixed to a vehicle or trailer;

an electrically conductive contact associated with the track and operably connected to a source of electricity from a battery or engine of the vehicle; and

a lamp assembly selectively positionable along the track and conductively coupled to the source of electricity;

wherein the track includes a first channel for receiving the lamp assembly, and a second channel having the electrically conductive contact disposed therein;

wherein the track comprises upper and lower tracks attached to upper and lower portions of a trailer of a semi-truck so as to be generally parallel and substantially surround the trailer; and

wherein the upper and lower tracks are both operably connected to the source of electricity, and a track attached to a cab portion of the semi-truck, wherein the tracks of the trailer and the track of the cab are electrically coupled to one another.

2. The system of claim 1 , wherein the track comprises a conductive material, and a non-conductive material disposed between the track and the electrically conductive contact.

3. The system of claim 2 , wherein the non-conductive material comprises an open-faced sleeve slidably received in the second channel and configured to receive the electrically conductive contact therein.

4. The system of claim 1 , wherein the track is comprised of a non-conductive material, and the electrically conductive contact is configured to be slidably received within the second channel.

5. The system of claim 1 , wherein the lamp assembly includes a lamp and an electrical connector extending from the lamp so as to physically contact the electrically conductive contact.

6. The system of claim 1 , wherein the lamp assembly comprises a base having projections configured to be slidably received within the first channel, a lamp, and a lens positioned over the lamp.

7. The system of claim 6 , wherein the lamp comprises at least one light emitting diode.

8. The system of claim 7 , including an electrical connector extending from the light emitting diode so as to physically contact the electrically conductive contact.

9. The system of claim 7 , including a reflector disposed between the light emitting diode and the lens.

10. The system of claim 9 , including a light emitting diode cover disposed between the reflector and the base.

11. A vehicle and trailer lighting system, comprising:

an elongated track fixed to a vehicle or trailer;

an electrically conductive contact associated with the track and operably connected to a source of electricity; and

a lamp assembly selectively positionable along the track and conductively coupled to the source of electricity;

wherein the track includes a first channel for receiving the lamp assembly, and a second channel having the electrically conductive contact disposed therein; and

wherein the lamp assembly comprises a base having projections configured to be slidably received within the first channel, a lamp comprising at least one light emitting diode, and a lens positioned over the lamp, and a reflector disposed between the light emitting diode and the lens.

12. A vehicle and trailer lighting system, comprising:

an elongated track fixed to a vehicle or trailer;

an electrically conductive contact associated with the track and operably connected to a source of electricity; and

a lamp assembly selectively positionable along the track and conductively coupled to the source of electricity;

wherein the track includes a first channel for receiving the lamp assembly, and a second channel having the electrically conductive contact disposed therein; and

wherein the track is comprised of a first set of substantially parallel and spaced apart channels adapted to receive generally opposite tongues of the lamp assembly, and a second set of substantially parallel and spaced apart channels in which first and second electrically conductive contacts are disposed.

13. The system of claim 12 , wherein the lamp assembly includes a lamp and a conductor extending therefrom adapted to selectively physically contact either the first or second electrically conductive contacts.

14. A vehicle and trailer lighting system, comprising:

an elongated track fixed to a vehicle or trailer;

an electrically conductive contact associated with the track and operably connected to a source of electricity; and

a lamp assembly selectively positionable along the track and conductively coupled to the source of electricity;

wherein the track includes a first channel for receiving the lamp assembly, and a second channel having the electrically conductive contact disposed therein; and

wherein the track comprises upper and lower tracks attached to upper and lower portions of a trailer of a semi-truck so as to be generally parallel, and wherein the upper and lower tracks are both operably connected to the source of electricity.

15. The system of claim 14 , wherein the upper and lower tracks substantially surround the upper and lower portions of the trailer and are electrically connected at corners thereof.

16. A vehicle and trailer lighting system, comprising:

an elongated track fixed to a vehicle or trailer;

an electrically conductive contact associated with the track and operably connected to a source of electricity from a battery or engine of the vehicle; and

a lamp assembly selectively positionable along the track and conductively coupled to the source of electricity;

wherein the lamp assembly comprises a base configured to be removable received within the track, a lamp comprising at least one light emitting diode, a lens positioned over the lamp, and a reflector disposed between the at least one light emitting diode and the lens.

17. The system of claim 16 , wherein the track includes upper and lower tracks attached to upper and lower portions of a trailer of a semi-truck so as to be generally parallel, and wherein the upper and lower tracks are both operably connected to the source of electricity.
