Informant: I know we did this in college, but you always have to leave what’s called a “ghost light” on stage. I think the idea is that if all the lights in the theater go out, it’s bad luck, like they won’t come back on the next day, so you leave one light on.

It’s literally just a single light bulb on a pole that rolls, and you place it on the stage when everything else is off.

Context : Informant has participated in main stage theater productions at the university and has experienced this superstitions themself. Informants knew about this superstition when they were in high school, but did not practice it until they were in college. Informant attends school in Southern California. 

Analysis: This is quite classic theater-based superstition. Traditions like the ghost light are widely recognized within theater communities and are passed down informally rather than taught in any official way. The ghost light functions as both a practical object and a symbolic one. While it may have a safety purpose (preventing accidents in a dark theater), it is also tied to a belief that leaving a light on wards off bad luck or ensures the theater will function properly the next day. This, while not a conversion superstition, is more of a ritual meant to prevent misfortune, even if participants don’t fully believe in the consequence.
