Hey y’all. First time posting here. I’ve got a 2019 KL latitude that I want to install a Whelen Legacy lightbar on. If you don’t know, Whelen makes lighting equipment for police cars and the like. But I only have amber/white colors. So this isn’t like adding one of the 40-42” offroad style lightbars with a small wire that can be done through the roof rack rivnut. I have two cables, and the power cable is just over 1/2”. Has anyone truly drilled a proper sized hole through their roof... Drilling roof for Whelen lightbar
