That's 20cents each, compare at $1 on the 'bay. These are NEW neon bulbs, for equipment panel lights from the old, pre-LED days. They run off 120Vac, with a 39K Ohm, 1/4W resistor soldered / crimped in-series. Glow is nice orange color, lifetime is over 5 Years. NOT incandescent, won't operate on direct current. They can be used to "quench" voltage spikes, somewhere around 70Volts if memory serves. An old circuit designer technique. Will also work off 220Vac, just ask me about the resistor value for that application. You can test all here first. Old school stuff.
