Yeah.  My experience flying around at night, even in the cockpit--"dim
lights" are okay, but the accomodation isn't that great.  If you do manage
to fully adjust (a process which can take up to 45 minutes), it can be ruined
by an instant of flash (explosion, strobe, the twit with the reading 

Even in the cockpit, lights-out is more for reducing the amount of glare/
contrast with the outside scene, and less with any goal toward night-
accomodation.  Some captains even like to have the dome light or panel 
fluorescents on all the way down.

Besides, odds are excellent that anything which causes a failure of the
emergency lighting system will be accompanied by considerable amounts of
dense smoke in the cabin; you'll be groping your way out in broad daylight,
