RCA 991 Neon Lamps
Here are some NOS 991 neon lamps made by RCA.
The 991 lamp is similar to the NE-16 / NE-48 lamp (two pin large bayonet base; T4-1/2).
The 991 was typically used as a voltage regulator (90V 15mA).
They can also be used as a regular pilot lamp.
They require a special two pin bayonet base.
These lamps are NOS (new/unused).
These are being sold individually.
There are five lamps available.
This part is sold as is (no return).
