How is neon used in lightning arrestors?

Answer:
Neon and other noble gases require a high voltage to conduct electricity, so that normally current will not flow across them. However, a direct lightning strike (such as on a radio tower antenna) will cause the neon to arc and conduct the massive amount of electricity to the ground, protecting transmitters and other equipment.
