Audio problem: When Michelle is taken inside by the gas station attendant, she thinks he is going to attack her. As she tries the locked door and he grabs her, we hear herscreams but her mouth doesn't match up to them. (00:06:35)
Audio problem: When Natalie shoots Brenda backwards, causing her to fly out of the window, we hear the sound of smashing glass as she flies out. However there was no glass; the window was missing and the hole was boarded up with planks, so we should not hear glass. (01:28:45)
Answer: This urban legend involves wannabe gang-bangers being required to make a kill to join the gang. In this scenario they drive with their headlights off and kill the driver of the first car that flashes their headlights at them. This was proved to be a false urban legend by snopes.com where more information can be found at http://www.snopes.com/horrors/madmen/lightsout.asp.
