Not that power input and light output are exactly the same but the Las Vegas sphere is 28MW

Good point, the lights on a boat or airplane (probably not a train) are red on the left and green on the right. Not sure how international that is.

My favorite mnemonic: “We have some red port left”

Left if you are facing direction of travel = port = the red light

So “here” is close enough for your needs. “There” is too far away to be useful.

Yeah, some people want to be seen as different to stand out from the crowd, but if you identify someone as being different it can be considered “othering”.
