Hidden levers are the best way in my opinion. Torches create particles that lag. More than levers anyway. (Source: EthosLab)

@x3ICEx Thanks for the comments. This was created months ago, today I'd do it differently, but thanks again for the ideas. And yes the third sign means exactly what you wrote ;)
