Phoenix X, I certainly understand where you're coming from, there, having experienced that first hand on a missed approach (and for a time, failing to climb), but also from an accident some years ago where a Cv580 on departure with an (apparently) faulty AH gently pitched down after initial climb; the factors you mention were also mentioned in the accident report.
Believe me, the only time the runway lights would be turned off in this situation would be if the runway was occupied.
My assumption would be that if you have comms problems, there's an above average chance you may have other problems, or at least distractions, therefore you'd be given priority to use the runway, which all being normal, at two mile final chances are you'd be first to use it anyway. So I'm referring to the abnormal, eg a breakdown on the runway.
Which would you rather risk? Certain collision with a vehicle at the midpoint, or possible disorientation attempting to transit quickly to missed approach mode?
