The red light doesn't mean anything outside of its context, really--it is "just" a red light (this mode of thinking is sort what Ni would believe). It only works because we associate red with lots of bad things. In general, the color tells us, through other unrelated contexts, to proceed with caution, to pay attention, or to stop.
Repetition is just one way to reinforce patterns and correlations between unrelated contexts. Pushing a lever doesn't really have much to do with obtaining food through some dispenser, but pigeons have learned the connection.
Assuming that one wants the truth is a decent starting point, though.
