The solution turned out to be that the killer had set up mirrors that reflected back to a single camera in this manner. An episode of Bones had the team wondering how the killer could be watching them regardless of where they were in a cluttered storeroom.So, while it is technically possible, it's highly improbable. While with a stable light source it is possible to rebound the light off of several mirror, it quickly starts to weaken to the point of being unnoticeable the further it goes, requiring the mirrors be almost right up next to each other.

Without a stable light source, you'd have to constantly readjust the mirrors due to the changing positions of the sun. While it does provide some light for the room, it isn't something that can be relied upon for being able to see through the dark. The basic idea of this trope was tested by the Mythbusters, albeit in the 'used to light a room' sense. Additional complications can include the beam killing the player if they touch it, so the player may also need to ensure that they have safe passage through it. May also happen with a laser or magic beam, or something else entirely. Simply put, this puzzle involves a room that contains a light source and a number of mirrors, and requires the player to position the mirrors in a way so that the light will bounce off them in succession and hit a target.
