Miniature Simulator Modules
Due to the wide variety of modeling scales, LEDs for use with these products are sold separately and can be found by clicking on the Lighting Products link at the left side of this page.
Two new LOW-VOLTAGE
have been introduced: The NLA803X series for analog (DC) operation,
and the NLD803X
for DCC Sound decoders with 3.3-volt accessory
functions and RC applications that use 3.7-3.8 volt batteries. These
low-voltage versions have a wide effective input voltage range of
3.2 to 16 (maximum) volts DC.
Fusee (trackside flare) Simulator
The N8070 is designed to simulate the shimmering light of a trackside flare (fusee) for either 2 series-wired LEDs or a single LED. Additionally, at power-on several short bursts of light occur followed by a brief pause to give the appearance of igniting the flares. This ignition sequence only occurs at startup and can be disabled entirely by connecting the input control to –DC.
Defective Sign/Light Simulator
The N8069 is a 3-output simulator that reproduces the effect of a flickering or defective light on its first output channel, with the remaining 2 channels being on continuously. This allows connected LEDs to be strategically placed in model signs to display this effect dramatically. It can also be used in building, streetlights, or railroad passenger cars for the same effect. How about creative placement in a back-lit building sign for a humorous effect.
Smaller than a decoder at just .31" x .31" and utilizing the industry’s smallest microcontroller and associated circuitry, these modules consume less than 500 µa (<1/2 ma). Typical peak operating current with LED(s) attached and running through full brightness curves range from 18-38 ma. This makes them ideally suited for operation when powered directly by a function output of any of today's HO, N or Z-scale DCC decoders. Input voltage range 6-18 volts DC, so they'll work with nearly every layout environment. On-board current limiting resistor and input wires included.
Simulator Booster Boards
Marslight & Super-Marslight Simulators
The Marslight modules (N8031/A) produce a highly realistic Mars effect which is very eye-catching. Output intensity varies from dim to full-bright through a triple-pulse timed to imitate side (reflective) shine as well as frontal shine of the oscillating Mars pattern.
The N8031A version of this module is configured with an additional output for an optional headlight. See Connecting in More Info to the right.
The N8031B Super-Marslight Simulator provides output for 3 LEDs to create the visual effect of an actual moving Marslight. See the video of effects in More Info above.
This simulator provides a single repeating burst, increasing and decreasing in intensity to accurately represent roof beacons like those made by Prime and Federal used by most railroads. The N8032 supports either yellow or red 20ma LEDs. The N8032A is for white or blue LEDs.
Supports up to 200mA and 18VDC per output channel
NEW LOW-VOLTAGE SIMULATORS SEE DETAILS BELOW
The tiny size of our Miniature Simulator modules above make them extremely versatile for all modeling scales. However, this size also limits output driving capability to 25mA at 5-volts DC per output channel. This is sufficient to support a very wide range of lighting effects.
This module generates a varying (bell curve like) intensity to accurately represent Gyralight motion, and is configured for white, incandescent, or yellow-white LEDs.
The B version is configured with an additional output for an optional headlight.
The N8033A version is configured specifically for red LEDs.
See wiring details in More Info to the right.
Utility Vehicle Flasher Simulator
The N8075 is designed
to generate lighting effects for either 2 pairs of
series-wired LEDs or
two individual LEDs.
It will simulate the
lights seen on many city vehicles.
If a single LED is used, it will simulate the strobe beacons seen on many
smaller utility vehicles such as a forklift.
Utility Vehicle Flasher Simulator
The N8075 is designed to generate lighting effects for either 2 pairs of series-wired LEDs or two individual LEDs. It will simulate the alternating strobe lights seen on many city vehicles. If a single LED is used, it will simulate the strobe beacons seen on many smaller utility vehicles such as a forklift.
However, there are many modeling situations where a particular lighting effect may be desirable if it can be reproduced on many LEDs (series or parallel groups) or LEDs that exceed the 25mA or 5-volts DC. This is where our Booster Boards shine (forgive the pun). At just 0.8" x 1.50", these small boards increase a simulator's output up to 200mA and DC voltage of 9-18 VDC. This greatly expands the versatility of many of our Simulator products. Although probably not a realistic application, imagine driving 50 or 60 LEDs with a Beacon Simulator!
The Boosters come in 3 flavors: N8103-1 to support a single output Simulator (i.e., N8032 Beacon), N8103-2 for 2 output Simulators (i.e., N8038 Early-era Alternating Flasher), and N8103-3 for 3-output Simulators (i.e., N8043 Universal Strobe). A Simulator is easily be piggybacked on a Booster Board (connecting wire included) and share a common power input for both..
Provides output for two LEDs, both on, then switches to alternating with realistic ramping of intensity when input is momentarily grounded (or activated by DCC function control). Re-grounding input returns LEDs to both on. Extra limiting resistors included.
Early-era Flasher Simulator
This simulator replicates the older-style signal and hazard warning flashers that used incandescent (filament) lamps to generate light. Typical flash rate of 3/4 second with a increasing and decreasing brightness curve to duplicate that of filament type lamps. Three outputs will each drive up to one pair (wired in series) of red and/or yellow LEDs Outputs flash sequentially so the module could also drive a very short series of "chase" lights.
Early-era & Modern-era Alternating Flasher Simulators
The 8038 series modules reproduce alternating flashes (with increasing and decreasing brightness curves) as seen in the older incandescent lamp driven type crossbucks used at grade crossings. The 8041 series simulate modern-era LED driven devices. All will drive up to two pairs of series-wired red LEDs without additional external circuitry. The N8041A will drive up to three pairs of series wired LEDs which alternate sequentially.
The first use of a FRED, or Flashing Rear End Device, is attributed to Florida East Coast Railway in 1973. Soon thereafter other Class 1 Railroads began using them as an alternative to the much-more-costly caboose. By the 1980's their use was widespread. Our module produces a flash rate and duration that replicates the prototype. See Connecting in the More Info table for a detailed explanation. For those using a battery as a power source, try our N8040A super-low current version. If you use a 1.75-2.0 volt, 20ma LED, the whole circuit draws only 3ma!
Steam Locomotive Class(isfication) Light Simulator
In typical applications, the forward-facing class lights on steam locomotives were used in three ways: For a scheduled train they would be dark, unless a second section was following, then they would be green. Trains running as extras were lighted white. This simulator allows all three conditions to be easily controlled using only one input. See Operating in the More Info table for a detailed explanation.
Rotating Beacon Simulators
These modules are designed to reproduce a highly realistic simulation of rotating beacons by sequencing LEDs (sold separately) that are positioned to produce the effect. See the More Info table to the right for complete information. The N8042 is for a 3-LED assembly that replicates typical beacons used by such roads as SP, WP, BN, and BNSF. The N8042C is for a 4-LED assembly that simulates the "gumball" type of rotating beacon. Both modules will support either yellow or red 20ma LEDs.
Universal Strobe Simulator
This simulator will support strobe effects for a wide range of locomotives, emergency vehicles and traffic situations. The strobe pulse is a short 70ms burst occurring either once per second on all three outputs simultaneously, or when the simulator input is grounded, on two outputs together and one output separately, alternating at one-half second intervals . See Examples of use in the More Info table to the right.
Flash Camera Simulator
To be a railfan (railway enthusiast) is to enjoy taking pictures of trains and railroad related scenes. Many modelers use scale people trackside to enhance their dioramas and layouts. This simulator will generate a flash camera effect when wired to a white LED. It produces 2 short burst pulses 2 seconds apart when the input is grounded, then delays 20 seconds before allowing the input to be retriggered. Input could be triggered by a passing train.

Furnace / Forge / Sawdust Burner Simulator
This module generates a slow, random undulating brightness output for either a single LED, or 2 series-wired yellow LEDs. The effect replicates the heat source glow seen in furnaces and wigwam (sawdust) burners. It can also be used to create a realistic firebox glow that would be seen in the cab of a steam locomotive or coming from a trackside steam skidder or donkey engine's boiler.
AUTOMATIC CURRENT PROTECTION!
At just 3/4" square, this product series includes a
state-of-the-art current source which provides a constant 20 ma for LEDs
connected to the module. This means any color 20 ma LED can be connected
without the need for external current limiting resistors,
multiple LEDs can be connected in series (requires a power source of
sufficient voltage) and different colors of LEDs can be combined in the
same series. All will operate at 20 ma.
For certain applications it may be desirable to
have the LED (or series string) connected to operate at less than full
brightness. For this purpose, solder pads are included on the back of the
module for placement of resistors to adjust of current source output.
voltage range 6-16 VDC. Extra power wires included.

This module creates an alternating flash between a pair (or pairs) of LEDs of approximately 3/4 of a second and 50% duty cycle. This is a typical sequence for standard modern-day grade crossings. This product supports "common anode" devices, see More Info for details.
Campfire / Fireplace Simulator
This simulator produces a random varying change in output intensity for either a single LED, or 2 series-wired LEDs that realistically mimics the crackling fire in a fireplace or of a campfire. Perfect for a trackside hobo camp or pile of debris in a yard cleanup operation. If used with our Nano LEDs even the smallest scale scene can enjoy the realism of this effect. This effect can also be used to produce the firebox flicker of a steam locomotive.
Produces a flash with a 50% duty cycle (equal on and off times). Rate of flash is adjustable from 30 flashes per second (33 ms) to one flash every 3 seconds. This adjustment is made by rotating the slotted center of a variable resistor (bottom right corner of flasher).
Catenary Spark Simulator
We have all watched electric locomotives, traction vehicles or trolleys as they move along the rails and have seen the sparks created by the pickups (pantographs or spring-loaded poles) as they travel along the overhead (catenary) wires. This simulator is designed to reproduce those intermittent sparks of varying intensity for either two outputs (for dual pantograph applications) or a single output, for one pickup like many early-era trolleys had. The tiny size of our Nano white LEDs are perfect for this application.
Variable-rate Alternating Flasher
This module creates an alternating flash between a pair (or pairs) of LEDs with a 50% duty cycle (equal on and off times). Rate of flash is adjustable from 30 flashes per second (33 ms) to one flash every 3 seconds. This adjustment is made by rotating the slotted center of a variable resistor (bottom right corner of flasher). This product supports "common anode" devices, see More Info for details.
Arc & Gas Welder Simulators
Finally, welding simulation that looks just like the real thing! A bit of shameless back-patting, but we believe it is warranted. These simulators are configured for connection of two LEDs to accurately reproduce the varying intensity, intermittence and slight color changes just like real welders. Our Nano LEDs are perfect for reproducing these effects. N8064 is the arc welder and N8064B is the gas welder. See Connecting under More Info to the right, for product details.
