I must say, Mark, that is a mighty fine looking SD9-3.

Chad!
Thank you for your compliments. Much appreciated.
As far as fitting a circuit board into a vehicle, I don't think it is always necessary to do that. I want to illuminate flashing turn signals on a few vehicles so I have ordered two different devices to experiment with.
The first is simple red flashing 5 mm LEDs. Hopefully I will be able to fit them inside the bodies of a couple of cars or trucks. I don't want to do too many because I feel the effect could be very easily overdone.
The second is a flashing circuit from Ngineering which can drive up to 6 LEDs which will likely be mounted below the layout:

This circuit is very small but may still be too big to mount inside an HO vehicle so I will simply mount it below the layout and run appropriate sized wiring to it. I will use the Ngineering circuit to illuminate the signals on a Canadian Pacific Mack B transport truck and trailer with a yellow LED feeding the signal light on the top of the front fender via fiberoptic cable, and two red LEDs on the cab and trailer signal lights which will be 0603 SMDs. The circuit actually has capacity for two such arrangements. I plan on using the second half for an Athearn Flxible Clipper bus which I just scored on eBay.
The downside to putting all of this wiring into HO vehicles is that there will have to be a hole in the layout below each vehicle big enough to allow the wiring and resistors to fit through. Instead of hard wiring each vehicle to a fixed location I will install connectors which will allow the vehicle to be moved from one site to another. If I size the holes to fit manhole covers, I will be able to remove a vehicle without leaving a big hole in the road.
I can't imagine what the wiring will look like below my layout! I just hope I can see it through the smoke!!

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
Chad, regarding polarity, if I am using magnet wire I have a combination spool from Ngineering that has both red and green wires. If I am using a larger guage wire like #30 I use a paint pen to mark one lead.

My last activity of the long weekend is to scan through all the pictures and smile. Thanks for all the contributions.
