The Operation Lights On has been incorporated into the AIM. That is only concerning Landing Lgts. From a non airline guy, I don't appreciate folks using supplementary strobes or ice lights on the ground at night. (Other than for a quick or preflight check) In flight, light it up. I generally always use a landing light below 10K, though I only use Ice Lights to take a peek or when transitioning ice.
