Route Indicator Circuit

So for some time I've been trying to come up with a simple way of indicating what direction a point is set too without too much trouble, fortunately I cam across this post on rmweb regarding using bi-color leds with electrofrog points.

Now the idea stayed floating in my head for some time, given that I had tried it with individual leds first but it wasn't quite something I was happy with.

Though as mentioned as I came across the post I decided to give it a go so I got all the items I needed from maplins.

Those being a breadboard, leds (bi-color type) resistors, tripad board, the diodes I already had from another project.

How the circuit appears on a breadboard

Then The process begins of putting it on a tripad board (like stripboard but each each track is separated into 3 holes)

Now you may have noticed there's no led on the finished board, thats what the orange and gray wires are for as they will go to the led mounted in the control panel.

The blue wire comes from the polarity switch in the point motor and the red and black returns to the dcc wires.

How this works is when the frog is set to the red polarity it will return through the black as power will get used by the led and vice versa and the diodes stop the circuit shorting out, and if the led shows the wrong colour I simply swap it round.
