The escape room wanted a breaker panel prop that was not brand new, but rather looked a bit used. 
This one is wired to look for certain breakers to be on, and others to be off, and when done correctly, it flashes a code on the LEDs, which will be a clue to the next puzzle or a lock, etc. 
Variations can allow for the game master to set their own switch pattern, and the result can activate other lights, magnetic locks, etc.
