Since your scenery base is styrofoam, when making your pilot holes you could use a skewer chucked into your drill motor. Most anyone who operates on a railroad has a bunch of those skewer uncoupling tools laying around. Using one to “drill” pilot holes makes a lot less styro-chips to vacuum up. Then chuck the appropriate size dowel in the drill motor to make the final hole (I’d sharpen the end in a pencil sharpener).

In reply to PAUL.

Hello Paul,

The resistors will vary depending on the current draw of the LED. I usually start with a 1K ohm resistor and adjust down from there to et equal brilliance in the LEDs.

Hope this helps,

Could you publish the wiring diagram for the small printed circuit board the has the diode and current limiting resistors?
TIA,
