Finished installing backup lights, other than a shorty antenna (parking garage only 7-feet) and line-X, this qualifies as my first "mod".
(pictures look a little bit fuzzy, they are thumbnails so click on one for more detail if you want)

I was able to use an existing hole to mount the lights, but had to remove the bumper-cover to get a tool to reach the nut.

I had to open the existing hole just a little bit to get the extension through, the socket would not fit through the widened hole.

They are Rigid brand lights, they tuck up there pretty well.

Ran the conduit through the frame, it comes out of an existing hole behind the right front wheel. I rant it to upfitter #4 to avoid them coming on in inappropriate locations like a parking lot.

I did not bother taking any night shots but they are more than bright enough for the backup light purpose.
