Corrected entry: When Billy is in the motel room trying to open the ATM machine with the axe, he takes a couple swings at it and accidentally hits the lamp causing the light to break and go out. As they cut to different shots of him swinging at the ATM, you see the light from the broken lamp going on and off. (00:44:50)

Correction: Broken lights often flicker on and off for periods of time.
