peahrensmy crossovers are wired like that; i.e., 2 parallel Tortoises with one bi-color LED off the DPDT, in series with the Torti.
rrinkerThey won't be over current, the Tortoise draws a max of 15-18ma which is below the maximum 20-25ma of most any LED.
if each tortoise draws 15ma, two in parallel will draw 30 ma.
need to make sure your LED can handle that

BigDaddy What is the learning curve on your CAD program and which one is it, Mel?

I used Anyrail - very easy but very basic.

Thank you also Freeway3
I probably had my 3 LEDs in parallel as well. I never end up taking step by step pictures of anything because I don't stop after each step. Just like the latest work on my layout, I intended to get pictures of tracing the backdrop curve onto carboard, cutting it out, then tracing it on the plywood before cutting. Nope. just a finished shot of the cut out piece of subroadbed. So the only pic of that panel is the finished form, no shot of wiring it up, or drilling the holes, or putting in the toggles and the LED bezels.
Sure I would have wired 3 bi-color LEDs in parallel, 2 facing one way, the third reversed, and the whole set then in series with the Torotise. The single turnout sidings were 2 bi-color LEDs, back to back antiparallel, in series with the Tortoise. So the selected one was green, the other route was red. Flip the toggle, the points moved, and the red and green LEDs switched. So both choices were illuminated, the one you were going on in gree, the blocked one in red, instead of just having an LED light for the selected route.

Yea! You got me! I screwed up, it’s 1 & 8.

Thanks Mel and everyone else! I got it wired and bench tested - all working
