'99 Lariat (chrome bumper). What are these oval holes for? Located on the little tabs, pointing forward on the bottom. I doubt they're strong/big enough for recovery ops.

They look like a nice place to add some aux. reverse lights. Surely Ford didn't have the foresight to add them for this purpose...

I've wondered this for a while, finally thought to ask. Thanks

 

Holds the bumber during the chrome plating process, notice the plating around those holes is often less than perfect?

 

I did notice that, thanks.
