Just received my DEPOT brand aftermarket '08-up tail lights.

They look GREAT! just waiting on the LED bulbs and the smaller socket for the reverse lights to install em.

What is the hole (covered) at the bottom of these lights for? is there another light on '08 up trucks that goes in there?

 

I am pretty sure ford put it there for up fitters who put strobes and things like that in plow truck, work trucks, etc.

 

Gotcha! Thanks!
