Mounting of short tube light bar mount

I want to mount 2 or 3 lights on the front bumper of my truck. I like the look of the brackets going through the bumper but I couldn’t find anything about cutting the bumper? In a couple pictures I’ve seen the bumper looks cut the same, so is the whole bumper aftermarket?

 

That is a stock bumper. Below the headlights are a couple blanks because the 'bumper fillers' are missing. You can find those for $10 ea on ebay. That light bar doesn't require any cutting as far as I can tell.

Removing the bumper is quite literally a 5 minute job; deep socket 14mm will set you free.

Here's a pic to show you what's behind that bumper -
