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.

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 for complete information.

Rotating Beacon Simulators

These module reproduce a highly realistic simulation of a rotating beacon by sequencing LEDs (sold separately) that are positioned to produce the effect. See LED Construction in the More Info tables to the right for complete information. The timing of the rotational effect closely replicates that of typical rotating beacons used on emergency, construction, utility and military vehicles. The N8042A version is configured for white or blue LEDs. The N8042C is for a  red or yellow 4-LED assembly that simulates the "gumball" type of rotating beacon

This simulator generates a rapid stream of pulses alternating between 2 connected LEDs whenever the input pin is grounded. The timing and duration of these pulses mimics the appearance of automatic weapons fire like that seen in WW2 and modern era ground and urban assault vehicles. The N8060A version of this module is configured for 4 LEDs alternating between pairs to simulate 4 guns firing.

We've all seen this in real life, hopefully, only as we are driving past. This module generates a rapid 4-pulse alternating strobe type flash for 2 common-anode wired LEDs to simulate the rear window emergency lights seen in so many modern-era unmarked highway pursuit and state police cars. The simulator has input control for hookup to a remote switch to activate the effect. The N8044A version has an additional output and control for alternating vehicle headlights (white LEDs).

This simulator generates a stream of pulses for a single LED whenever the input pin is grounded. The timing and duration of these pulses mimics the appearance of machine gun fire for early (slower rate) guns that were used on World War 1. The "A" version is for two LEDs that fire alternately, simulating two guns.

Super Flashers

This module reproduces blinking turn-signals or flashing hazard lights for 4 LEDs (2 amber & 2 red). LEDs are wired as two series pairs. The flash rate replicates most standard signals for passenger vehicles and trucks. As shown in Connecting in the More Info tables to the right, by connecting external switches to the module's input controls, full selectable operation for left or right signals, or hazard flashers is available.

How often have we seen a roof-mounted strobe-bar on a police vehicle from a mile or more away? Very eye-catching to say the least This circuit will sequence 6 LEDs in rapid strobe-like fashion, simulating the effects of typical police vehicle roof-mounted strobe bars. The configuration is quite dazzling in appearance and is intended for two white, two blue and two red (or yellow) LEDs.  The N8072A is for two blue, two yellow & two red LEDs.

This simulator generates the eye-dazzling effect seen emanating from various emergency vehicles such as ambulances, rescue vehicles, fire trucks and airport runway service vehicles. It is configured to drive 2 series-wired red LED pairs that alternately strobe in rapid 4-burst pulses. A 5th white LED strobes 3 times independently during each complete cycle. This creates the highly eye-catching effect. For prototypical LED placement see Placement in the More Info table to the right.

Custom Lighting Effect Simulator

Do you need a special lighting effect that that no one produces or have a unique prototype requirement? We may be able to help. The N8050 will support 1 LED output, the N8051, 2 LED outputs, and the N8052 will support 3 LED outputs. For an additional programming charge (quoted separately), we will program the appropriate simulator to create your effect. Just email or call us with your requirements. We will review them, determine if they are within the capabilities of our simulator, and if so, respond with our quotation. Delivery can be within 2 weeks and our quote will be reasonable.

This simulator will sequence 6 white or yellow-white LEDs in two different ways. With the input control pin left unconnected, LEDs will light in succession (1 through 6) then repeat over and over. With input control grounded (-DC), LEDs will sequence in an up and down fashion (1,2,3,4,5,6,5,4,3,2,1) and repeat over and over. The N8049A version is for red and/or yellow LEDs. Modern construction vehicles use lighting boards with this type of lighting sequence to direct traffic.

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.

Input voltage range 6-16 VDC. Extra power wires included.

This module is designed to produce a short "burst" flash of approximately 1/15 of a second (65-70 ms) at a rate of two times per second (2 Hz). This approximates strobe flashers used on modern-era emergency equipment such as fire trucks, police cars and ambulances.

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).

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.

This simulator will sequence 6 white or yellow-white LEDs in succession (1 through 6) then repeat over and over when input control is grounded (-DC). Unlike the chase light Simulator above, this version can be cascaded together for a virtually unlimited chase sequence. Click on Connecting in  More Info (to the right) for details of wiring and operation. The N8049D version is for red, orange, and/or yellow LEDs.

Beacon Simulator

This simulator provides a single repeating burst, increasing and decreasing in intensity to accurately represent a warning beacon.  The standard module N8032 will support yellow or red 20ma LEDs and when used with red,  it is an excellent choice for earlier-era police cars, fire trucks and ambulances. The N8032A version of this module is configured specifically for white LEDs, and the N8032B has 2 selectable speeds.

Arc & Gas Welding 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.
