Lightning Trailer 1/87 scale (H0)

thingiverse

This is a trailer in 1/87 (H0) scale that shines with a small model scene without relying on external lamps. The LEDs are bright enough to provide some fantastic night flair. For the lighting, I used 5 Neopixel RGB LEDs and 2 red SMD LEDs (type 0603). 4 of the Neopixels illuminate the surrounding area of the trailer from the top of the mast, with individually adjustable color and brightness. The fifth Neopixel lights up a screen on the side of the trailer. The two red LEDs serve as rear lights, using 470Ohm series resistors. The brightness of all LEDs and the color of the Neopixels are controlled by an Arduino Nano.

Using enamelled copper wire seems like a viable solution.
