Letters with flexible neon STEEL LED LETTER from RH
The scene represents the entire alphabet of capital letters, the entire alphabet of lowercase letters and numbers.
The backlight has three colors, yellow (default) red and blue. To change the color, remove the color with a pipette from the ball in the scene, ungroup the letters you need, select the backlight (without the letter itself) and apply the desired color on it.

Also present in the scene wire. He is separately because mounting letters can be made with hidden wiring. If you need a wire, lay it in any way you like, for example, on a spline.
