Whats this?

I was cleaning up My FiST and noticed two little sideways H's on the lower windshield in the area circled below. Does anyone know what these are?

You cant see them in the pic, I could only see them at an angle under a certain light.

I never noticed that before..looks like some sensor.

Still dont know what it is but here is a clean shot of it

I asked the same question, this is what I was told.

They're called "tooling marks" and it's from something being set on there when the final coating was being put on and it didn't get painted.

That actually makes perfect sense. Here I was thinking it was some obscure non-serviceable sensor that wasn't even listed in the ford catalog. Nope, just part of the glass that wasn't painted.
