What is claimed is: 1. An airport light installation comprising: an airport light support having a coupling; an elongate column having a proximal end attached to the coupling, an opposing distal end, and a frangible area formed in the elongate column between the proximal end and the distal end, the frangible area providing a point at which the elongate column will break when struck; and a light fixture carried by the distal end. 2. The airport light installation of claim 1, wherein the proximal end is removably attached to the coupling. 3. The airport light installation of claim 2, further comprising a locking element carried by the coupling and movable between a first position releasing the proximal end from the coupling and a second position securing the proximal end to the coupling. 4. The airport light installation of claim 1, wherein the coupling is removably attached to the airport light support. 5. The airport light installation of claim 1, further comprising the coupling threadably secured to the airport light support. 6. The airport light installation of claim 1, wherein the frangible area is disposed outboard of the coupling. 7. An airport lighting system incorporating the airport light installation of claim 1. 8. An airport light installation comprising: an airport light container; a lid, having a coupling, removably attached to the container; an elongate column having a proximal end attached to the coupling, an opposing distal end, and a frangible area formed in the elongate column between the proximal end and the distal end, the frangible area providing a point at which the elongate column will break when struck; and a light fixture carried by the distal end of the elongate column. 9. The airport light installation of claim 8, wherein the proximal end is removably attached to the coupling. 10. The airport light installation of claim 9, further comprising a locking element carried by the coupling and movable between a first position releasing the proximal end from the coupling and a second position securing the proximal end to the coupling. 11. The airport light installation of claim 8, wherein the coupling is removably attached to the lid. 12. The airport light installation of claim 8, wherein the coupling is threadably secured to the lid. 13. The airport light installation of claim 1, wherein the frangible area is disposed outboard of the coupling. 14. An airport lighting system incorporating the airport light installation of claim 8. 15. In an airport light installation including an airport light support and a coupling carried thereby, improvements therein comprising: an elongate column having a proximal end attached to the coupling, an opposing distal end, and a frangible area formed in the elongate column between the proximal end and the distal end, the frangible area providing a point at which the elongate column will break when struck; and a light fixture carried by the distal end of the elongate column. 16. The improvements of claim 15, further comprising the proximal end removably attached to the coupling. 17. The improvements of claim 16, further comprising a locking element carried by the coupling and movable between a first position releasing the proximal end from the coupling and a second position securing the proximal end to the coupling. 18. The improvements of claim 15, further comprising the coupling removably attached to the airport light support. 19. The improvements of claim 15, further comprising the coupling threadably secured to the airport light support. 20. The improvements of claim 15, wherein the frangible area is disposed outboard of the coupling. 21. An airport lighting system having an airport light installation incorporating the improvements of claim 15. 22. In an airport light installation including an airport light container, a lid removably attached to the container, and a coupling carried by the lid, improvements therein comprising: an elongate column having a proximal end attached to the coupling, an opposing distal end, and a frangible area formed in the elongate column between the proximal end and the distal end, the frangible area providing a point at which the elongate column will break when struck; and a light fixture carried by the distal end of the elongate column. 23. The improvements of claim 22, further comprising the proximal end removably attached to the coupling. 24. The improvements of claim 23, further comprising a locking element carried by the coupling and movable between a first position releasing the proximal end from the coupling and a second position securing the proximal end to the coupling. 25. The improvements of claim 22, wherein the coupling is removably attached to the lid. 26. The improvements of claim 22, wherein the coupling is threadably secured to the lid. 27. The improvements of claim 22, wherein the frangible area is disposed outboard of the coupling. 28. An airport lighting system having an airport light installation incorporating the improvements of claim 22.
