Blast From the Past - Door Lock Indicator
Approx 30 min from the beginning of the movie, they are all sleeping in the shelter and the door locks are released by the automatic system. The camera takes a shot of the indicator lamps. The red lamp turns off and the green lamp goes on. They wake up and go to this door. When they open the door wide you can see on the right hand side of it that the red lamp is still on.
