Our HO Scale Grade Crossing Signal can be lighted with our 603 LEDs (4 each) in the head housings and the 402 LEDs in the arm (3 each), both 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 12', 16' or 20' signal arms. A pushrod and clevis assembly simplifies the means to animate the signal arm. You will need a servo controller and flasher circuit to fully animate the signal. The kit also includes a magnetic "break-away" base. Please click the videos tab to see this signal in operation. You may also view the instructions by clicking the instructions tab.
