Well even though we are on a family holiday there is still time to do some modelling and in this case it is the wiring up of the coloured light signals that I have been looking forward too. I have extended the wires of the LEDs so that they will be long enough to penetrate the layout board using Kynar wire soldered to the LED wire ends and covered with heat shrink tubing to prevent shorting. Each LED had its own wire soldered to its respective cathode so I have made one common cathod for the whole signal and all six LEDs by soldering a single black wire to the six white wires which will simplify wiring.

While I am currently not planning to use the Digitrax SE8C signal board I have adopted the Digitrax Terminal Strip Mounting Kit (TSMK) which per the photo you can see offers screw terminals for the signal wires plus a set of surface mount SMD resistors of 100 ohms each per LED and a 10 pin (2 x 5) IDC male connection. This IDC along with some rainbow ribbon cable will be used to run the wires from the signal to the Signatrak CML SIGM20 control board.
