PRR style signals27. November 201727. November 2017mike

A working PRR style position light signal in N-Scale ?

My current effort is to make this model available at least for my C&E layout where I need want to install signal protection on two junctions.

At present I spent more than 150 hours of labor and research into this project, starting back in 2016 with an idea on charlieplexing 16 LEDs needed by a full aspect PL.

With this I could reduce the 16 x 2 wires to only 5 wires for the full mast.

Below are two sample vids

First test with 3 mm LED and individual control :

Second test with 0402 SMD in an scale signal head :
