6 Vintage Good Condition Neon Pilot Bulbs

Great condition, bulbs for vintage electronics and radio.

The image shows miniature neon lamps (or glow lamps) with wire leads.
These are gas-discharge lamps that produce an orange glow when sufficient voltage (typically 90V or more) is applied across their electrodes.
They are widely used as indicator lights in electronic instruments and appliances due to their simplicity and low power consumption.
The lamp typically consists of a small glass capsule containing a mixture of neon and other gases at low pressure and two electrodes.
In DC applications, only the negative electrode glows, which allows them to be used to determine the polarity of a DC source.
