To avoid the burning up and oxidising of the tungsten filament in air.
Try to break the glass bulb of a 12V car lamp carefully.
Turn it on via a 12V supply, and it lasts about 1/2 second with a puff of smoke from the burning filament. |

Adding to these points the main reason is,
The interior of the lamp having the support wire sub assembly must be sealed from the environment in vacuum-tight manner, cuz hermetically sealing the lamps at places where wires or like metal parts extend from interior of the lamp to the outside has always been a problem in the art
and so support wire sub assemblies for incandescent lamps are usually
kept entirely within vacuum tight... _________________ http://blog.elitesat.com = "HughesNet Blog"
