Vehicular lighting system

1. A vehicular lighting system housing comprising:

an extrusion forming a first channel and a second channel;

a lighting system in the first channel adapted to direct light away from the first channel;

a mounting system in the second channel adapted to couple the extrusion to a vehicle;

a first end cap including a first connector, the first end cap being coupled to a first end of the extrusion such that an interior of the housing is sealed; and

a second end cap including a second connector, the second end cap being coupled to a second end of the extrusion such that the interior of the housing is sealed, wherein the first connector and the second connector are electrically coupled to one another, and wherein the first connector is configured to receive a first insert and, upon removal of the first insert, receive a second insert different from the first insert wherein the first insert and the second insert are each selected from the group consisting of power source wiring configured to connect the lighting system to a power source, connecting wiring configured to electrically connect the lighting system to another housing, and a receptacle plug configured to protect the lighting system, and wherein the second connector is configured to receive the first insert and, upon removal of the first insert, the second insert, whereby the first insert may be received by each of the first connector and the second connector, and the second insert may be received by each of the first connector and the second connector.

2. The vehicular lighting system housing of claim 1 wherein the lighting system includes a first light source and a second light source, wherein the first light source and the second light source are adapted to be independently switched on and off so that only the first light source, only the second light source or both the first light source and the second light source can be illuminated.

3. The vehicular lighting system housing of claim 2 wherein said lighting system comprises:

a first reflector adapted to generate a first beam pattern; and

a second reflector adapted to generate a second beam pattern;

wherein said first reflector is adapted to reflect light from the first light source; and

wherein said second reflector is adapted to reflect light from the second light source.

4. The vehicular lighting system housing of claim 1 wherein the first connector is coupled to a power source.

5. The vehicular lighting system housing of claim 4 wherein the second connector is connected to another lighting system in another housing.

6. The vehicular lighting system housing of claim 1 wherein said mounting system is rotatable about an axis of rotation outside said second channel over a range of at least 100 degrees.

7. The vehicular lighting system housing of claim 1 wherein the housing is a first housing and the second connector is coupled to a connecting wire received by the second connector, and further comprising:

a second housing substantially equal to the first housing, wherein the connecting wire is received by a first connector of the second housing, whereby the first housing is electrically coupled to the second housing.

8. A vehicular lighting system comprising:

a first housing comprising:

a first lighting system;

a first mounting system adapted for coupling the housing to a support;

a first end cap coupled to a first end of the first housing such that an interior of the housing is sealed;

a first connector coupled to the first end cap and configured to receive a first insert and, upon removal of the first insert, receive a second insert different from the first insert, wherein the first insert and the second insert are each selected from the group consisting of power source wiring configured to connect the lighting system to a power source, connecting wiring configured to electrically connect the lighting system to another housing, and a receptacle plug configured to protect the lighting system;

a second end cap coupled to a second end of the first housing such that the interior of the housing is sealed;

a second connector coupled to the second end cap and configured to receive the first insert and, upon removal of the first insert, the second insert, whereby the first insert may be received by each of the first connector and the second connector and the second insert may be received by each of the first connector and the second connector;

a second housing comprising:

a second lighting system;

a second mounting system adapted for coupling the housing to the support;

a third end cap coupled to a first end of the second housing;

a third connector coupled to the third end cap and configured to receive the first insert and, upon removal of the first insert, the second insert;

a fourth end cap coupled to a second end of the second housing;

a fourth connector coupled to the fourth end cap and configured to receive the first insert and, upon removal of the first insert, the second insert, whereby the first insert may be received by each of the third connector and the fourth connector and the second insert may be received by each of the third connector and the fourth connector; and

a connecting wire coupling the second connector to the third connector and received by the second connector and the third connector, whereby the first lighting system is electrically coupled to the second lighting system.

9. The vehicular lighting system of claim 8 , wherein the second housing is connected to at least another lighting system in another housing.

10. The vehicular lighting system of claim 8 wherein the first connector is coupled to a power source.

11. The vehicular lighting system of claim 8 wherein the first housing is coupled to a first mounting system adapted to couple the first housing to a vehicle, and wherein the second housing is coupled to a second mounting system adapted to couple the second housing to a vehicle.

12. The vehicular lighting system of claim 11 wherein the first mounting system is rotatable about an axis of rotation relative to the first housing over a range of at least 100 degrees and wherein the second mounting system is rotatable about an axis of rotation relative to the second housing over a range of at least 100 degrees.
