A few days ago I watched Pulp Fiction again. I noticed something and now I'm curious about a little detail. When Vincent and Jules killing Brett in Pulp Fiction a yellow/orange light appears two times but they fire definitive more than two shots.
In Rear Window (1954) Jeff repeatedly sets off his camera flashbulbs, temporarily blinding Thorwald. And the light when Thorwald gets blinded looks like the flashing light in Pulp Fiction.
Maybe that's a reference but doesn't answer the question why the flashing light in Pulp Fiction is asynchron to the shots fired at Brett.
