I have three Piko Siba semaphore signals which I would like to wire up and get working.

I understand there are two wires via a momentary switch to operate the signal, and two wires
to operate the LED's. Simple enough.

However, having done a search on the web, and coming up with nothing, I need to know
which wires goes where on the signal base. There are two wires pre-connected and four
spring-type connections. I don't want to blow the LED's.

Has anyone experience of wiring these please?

Sure there's only four wires? What about trying this article showing five connections?

Four spring clamps plus the two already attached wires. The picture though does give me a good idea - thanks!
