I have my lightbar wired into the highbeams, but also have a override switch inside to turn it off.
It's just the basic switch that came with the kit, but I'm happy with it. For where I located the switch you need to put a hole in the visible dash panel, but also need to carve out the panel that is placed behind it as well.
I'm happy with what I have, but I saw a image posted somewhere of a person using a switch that nearly looked factory but couldn't figure out where it was from so I didn't do it. I recently found the switch at tractor supply. I like the look and flush look of this switch, but don't know if it is the same diameter, and question how much deaper it is then what I have.
