Light 'em up!
The way I was trained was to wrap the airline around the pintle hook so that if the glad hand.comes loose.you aren't dragging it down the interstate for a few hundred miles.
When you pretrip your front box you should be checking the pintle hook's action as well as the grommets on the glad hands, since you have everything already open you can then route the hose up and around so that when/if you yap the dolly nothing gets pinched.
Same when you pretrip the dolly, you check the glad hand grommet then route the line so that it won't get pinched.
Personally, when I drop my back trailer and post trip it I open up the pintle and route the line so that the guy behind me is already to go, same with my lead after I drop the dolly.
I agree that when you pre-trip the front box, you can make sure the hose is not wrapped around the front of the pintle hook. But here is a scenario.
Both trailers are on doors for sort down. You have spotted your dolly in front of the rear trailer and pre-tripped it. You are hooked to the front box and inside waiting on the door to close.
When you verify the door has been closed and latched, you go to your tractor and pull it off the door. Yes, you can pull it off a few feet and then pre-trip it checking for the hose wrapped around the pintle hook.
Or you could pull it off and spot it in front of the dolly. Now you can pre-trip the front, checking the lights as you throw the dolly on the pintle hook.
If the hose was wrapped, and you misjudged the distance, you could puncture the hose if you tap the dolly while backing the front to the dolly.
While we are paid by the hour, I don't know many drivers who want the extra step of pulling the trailer off the door, getting out and checking the rear, then getting back in and moving it to the front of the dolly and then getting out again.
Even if you wrap the hose around the pintle hook, it is still going to drag on the ground if it comes off the trailer glad hand. There is more distance between the trailer glad hand and the pintle hook than there is between the pintle hook and the ground.
I am glad to see that you set it up for the next guy, running the hose up and over the top rather than wrapping it around the pintle hook.
