I've got a Simpson Carrier level meter with a brighter green glow, Brian.
In fact, one or two of the BFO vernier dials here used for the RATT mod
have the 'luna moth green' glow. I don't think they're radioactive, though.

More interesting, a Line level meter I have actually glows blue. The needle
and legend are a light tan color in the natural light. No markings beyond
Type 8, O(or Q)VS Inc., mod 150, and SEALED DO NOT OPEN. Asked about it
here some years back, no one knew. Would love to find a Line level meter to
match it.

It's a purty blue color, too. Really stands out.
