Just noticed this on several cars, was it used or intended for a light ?

For measuring body/suspension location. Suspension console.

Tank hold down strap attachment point.

I'll go back to sleep. I thought it was in the engine compartment.
I'm sitting in the dentist chair.

My tank strap is installed ? I don’t see the connection....

vent from the 2 pieces being welded together?

or I think the gas tank strap nut is on the other side, so space for a longer bolt?
