Light under dash after startup

[67D100Pickup]

On my 1967 D100, a light comes on under the dashboard near the radio after I start the engine. It stays on about 1-2 seconds.

What the heck is that?

Could it be a light that should be plugged into the back of the instrument cluster but isn't? Like the oil light.

What does the bulb look like?

BINGO!

I had knocked the oil pressure light out of its socket while working on the speedo cable.

Good job!
