K & R Custom Models 101 Model Searchlight Signal O Scale

Models are custom made (3D printed) and hand painted. Signals have 4 hidden holes on the base for locking down your signal on your application. Contains all the electronics to detect a ground relative to your power system voltage. Many K & R signals can be driven by other competitors' ground detectors and optical equipment. The "Searchlight" products have a single light source in each head that simulates green, yellow, and red. This is controlled by a triggered ground that you use relative to your power sources or isolated track rail.

A green light indicates a clear track. That green light changes to a bright red by a ground trigger to indicate a busy track. When the track clears (lifting of the ground trigger) the light changes to a bright yellow for at least 10 seconds and then turns green unless another ground trigger is received.
