Our N Scale Grade Crossing Signal can be lighted with our 402 LEDs (4 each) sold on the drop-down menu paint/tools….AND….it contains parts for you to make it operate! The kit will include stainless photo-etch details, brass tubing, pewter, and resin parts to make ONE SIDE crossing. The movement of the arm in the video is done manually. If you want the arm to be operational you will need a controller. This kit can be built with or without the arm and includes your choice of a 12', 16' or 20' arm.
