He probably still does. The brake lockout isn't particularly important when
backing down a ramp, where there will be little or no pressure on the
coupler to push the boat/trailer.

That being said, if the lights are sealed, there's no reason to unplug them.
I never unplug mine. Nor have I ever needed to use the manual brake
lockout on my trailer. I expect I would if I were to back up a hill though.
