It has been a while since this thread was active but I just wanted to throw in my idea of placement. I did not install everything yet, just hooked up the wires and tested, nothing screwed in, but I thought of a nifty little place to put them. In the removable area on the outside of the fangs you could drill a small hole, or just take a little bit of the outside off and run the wires. You could mount the bracket back inside the bumper so from the side it looks flush and is only visible from the front.

I test fitted the lights with some tape on mine and it looks great. You could even go as far as to throw some night shade on them too so when they are off it is completely hidden.
Just an idea I thought up.
