High quality signals typically make up 66%-75% of the cost of a signaling system. John Plocher made these simple snap-apart PC board signals to sell for less $1.00 each! These signals let you implement a signaling system for a third the cost of a full system with "model" signals and prove out your design without a large investment. These signals can be installed before scenery and treated as disposable. Also see our low (dwarf) signals and high two head signals.
Surface mounted Red, Yellow and Green LEDS come installed in a common anode (+) configuration. No limiting resistors are provided but our cpNode and IOX adapters have pads for resistors. This arrangement lets you choose the voltage (we recommend 5V, but other voltages will work fine with suitable limiting resistors. We use commodity LEDs for these signals so colors may not exactly match your prototype or be uniform brightness. 0.100 spaced solder pads are provided for your own wiring.
