I started a new thread as the previous one is now at 2 pages and getting rather lengthy. (See below : Railroad Lights, what do I have?)
I finished the Block Light and it is operational as per the suggestions offered: Top to bottom: Green light, then Amber light, then Amber light flashing, then a change to Red light; repeats.
It's a fun little addition to my shop. Thanks to those who offered suggestions/comments. Wouldn't/couldn't have finished it with out your help. Let me know what you think.
