Been looking for light upgrade ideas. Need more light in some occasions. I'v seen some putting leds in the holes next to the fog lights in the bumper. Question is, are these lights legal to use on the highways and should the holes in the bumper be left unrestricted for air flow. I'v also looked at puttin a 40in bar atop the cab under the lumber rack. Pictures of the install are hard to find! Dont want to start lookin too over accessorized!
