A convex glass cover over a glowing light is always an indication that an A.I. will go rogue
A ubiquitous Shout-Out to 2001: A Space Odyssey used so often and in the same context to qualify as a visual trope. Anytime there is an A.I. in a work, and that A.I. has a physical body of some kind, and that physical body has an "eye" that can be described as a glowing colored light (usually red) behind a convex glass screen, then that A.I. will invariably go rogue and try to do stuff people don't want it to do. What's unique about this trope is that the A.I. always starts out fine, and then goes rogue over the course of the story, rather than starting out rogue to begin with... just like HAL.
