You could mount lights in there also. But, I'm making the JDM style light bar that will mount above the skid plate to mount thin mount 5.5" lights
I also am taking out my parking lights and installing peterson 2"or maybe the 2.5 tunnel lights since the are chrome looking when off and will match the driving lights.
Here is what they look like.


I also am replacing the rear reflectors with the set of red ones and thinking about the side red ovals with these
