Sorry man, I've been pretty busy and still am kinda. I have a partial but its not very good.
Since I have the XLT I have the black trim on the bumper so I mounted them there and they don't stick out. A guy I work with has ones that he mounted into his chrome bumper and they look fine, only after a while it started to rust around since he didn't paint or treat the exposed metal.
But since your 03 I assume the bumper is plastic or fiberglass or something. I have seen them available in different colors. Although if you could find something black or white or any other basic color they'll blend in easier than a shade of green, lets say. Since there are generally more.
Thats the side with the off one, the far right is down more than the others.
