HO Scale Little Lights PL Lower Signal
These are some of the most authentic functional PL signals available in HO scale! Each model features realistic design elements, taken from original technical drawings of the real thing. These lower signals are based on the PL-2 design, and feature a scale 52" diameter face. The individual lights and wires are mounted using a realistic conduit "spider", which routes the individual wires out the back of the model.
This signal can be prepared as the full lower signal, which includes 7 LEDs that make up the vertical, upper quadrant, and lower quadrant positions. Additionally, all derivative forms of this signal are available, which may be more prototypically accurate for a given scene.
Each signal comes with several different brackets which can be used to mount to standard tubing. These brackets can mount to 1/16" tubing (scale 5.43" diameter) or to 1/8" tubing (scale 10.88" diameter). Plastic tubing is recommended over metal, as the metal tubing has the possibility of damaging the wires.
These signals come with a latex masking pre-applied over each lens. This mask protects the lens from paint and weathering materials. This makes it extremely simple to paint and weather the model out of the package! Once painting is complete, simply remove the mask with a pair of fine tweezers, leaving the pristine lenses underneath.
This model comes pre-wired, so there is no need to fight with small LEDs or wires! Each model uses 38 gauge wires to power the LEDs. On each LED, a red wire denotes the positive anode, and a yellow wire denotes the negative cathode. The wires are approximately 24" long, however the wires are provided trimmed to different lengths to distinguish the different LEDs. The longest wires correspond to the center light, the next longest wires correspond to the lower quadrant LEDs, the next longest wires correspond to the vertical LEDs, and the shortest wires correspond to the upper quadrant LEDs. The wires are pre-tinned, and ready for installation!
This model uses 2 volt LEDs rated at 20 mA. To power the signal at 5 volts, resistors larger than 150 ohms are required. To power the signal at 12 volts, resistors larger than 500 ohms are required. We recommend using 560 ohm resistors.
We have replicated a great many permutations and variations of these PRR position light signals. That being said, if there is a specific configuration you need that is not in our catalog, please contact us. We will be pleased to help develop a signal to meet your specific needs! Additionally, we can assemble these signals in a PCL colored version, as used on the Northeast Corridor. This version is still in development, but will be available soon as its own product!
