The wire is made of wolfram, which can withstand the extreme temperature in 
the wire without melting. Provided of course that there is vacuum inside 
the light bulb to make sure it won't burn.

Another evidence of the head being a light bulb is in the Barks' story 
where Gyro  invents a firefly tracker that does not impress anyone. But 
when it proves to be able to predict meteors and Gyro prevents a train from 
crashing into one, he becomes the hero. And what did he use to warn the 
locomotive driver in the dark?
He waved helper with the head fully lit. Only a light bulb can do that. Not 
a vacuum tube. But then again, a light bulb is really a vacuum bulb.
