you can only ever have fog lights on when it is foggy. otherwise you will get pulled, and it draws attension to you as it is a boy racer thing to do. lol
i have been pulled once for forgettin to turn them off after bein in fog, and they cops said they will keep it on file and if they catch me again they will give me a fine.
so betta to do it on a switch.
even if it is a air craft style switch on the console.
