Some tubes do that. It was mentioned somewhere in the thread that it's a mercury rectifier tube.
Well, and many normal tubes look somewhat similar when they're faulty. See >>1143051.

Some people put LEDs inside tube sockets to make them look "nicer". Can't say I'm a fan of the practice, but whatever. Pic related.
