Thanks Doane and Les...
My lighting plans are very simple & uses minimal components.
The electrical schematic shows what and how I'm using a 9 volt power supply, the LED's and voltage dropping resistors.
You can add more lights and resistors and the same wiring for more lights...
I use copper tape strips as busses for the 9 volt positive side, and 9 volt negative side. I solder a resistor in between the negative side voltage and the negative side of the LED. The strips wrap around the interior of structures for ease of installation. Kind of like a GIANT circuit board.
The LED's are 0603 SMD (surface mount devices)....and run at 3.2 volt and have a 20 milliamp draw.(which is close to full brightness).
A wall wart 9 volt supply is connected to the copper tape strips. I use black and white hook up wire to interconnect everything.
The entire build was documented on another forum.
