The lights are the message
To an approaching driver, the flash pattern is the only thing that says this is one operation and nobody should drive between the trucks.
All SWS snow plow packages now come with
One clock for the whole plow train.
LinQ uses GPS time to keep every equipped truck on the same flash, with no truck-to-truck radio, no vehicle pairing and no fleet setup.
Proudly Canadian owned and operated. Engineered, built and shipped from Niagara Falls, Ontario.
SWS snow plow packages are engineered to meet or exceed the TAC Snow Removal Equipment Visibility Guide and applicable provincial snow removal guidelines.
Simulation
Switch between them to compare
Without LinQ: three trucks, three clocks. Drivers read three separate hazards and look for a gap.
Why sync matters
Warning lights should guide, not distract.
Plows work in trains: several trucks staggered across the lanes, clearing the road as one machine. SWS packages already keep every light on a single truck in step. Until LinQ, nothing kept one truck in step with the next.
Out of step reads as separate hazards
Three trucks blinking on three different clocks look like three unrelated obstacles, and drivers try to thread the gap between them.
In step reads as a wall
One synchronized pattern across the whole train reads as a single moving closure. That is what LinQ gives every driver behind your fleet.
How it works
Give every truck the same clock.
The trucks never talk to each other. GPS time is the same everywhere, so each LinQ truck works out the same flash frame by itself.
Step 1
GPS time
Time and heartbeat
The GPS module listens to the satellites. It hands the minibar the time of day, a heartbeat once a second, and a flag saying whether that time can still be trusted.
Step 2
TX front minibar
Calculates the flash frame
It works out which frame of the pattern this instant belongs to, and eases itself back into place if it has drifted.
Step 3
Existing lights
LIN network follows, with ArctiQ fail-safe
The rear bar, warning sticks and beacons follow the front minibar exactly as they do today. Same firmware, same wiring, same part numbers.
We use the clock, not the map.
LinQ reads the GPS time signal only. It does not track the vehicle, and it does not record or report where a truck has been.
Inside the truck, LIN. Between trucks, LinQ.
For years the front minibar has kept every light on one truck in step over a wired LIN network. LinQ carries that timing across the whole train without a single wire between vehicles.
What crews get
Built for a real plow yard on a snowy morning.
Upgrade one part only
On trucks already running an SWS snow plow package, replace the front TX minibar only. Same truck. Same wiring. Same lights.
Power it and go
Nothing to commission. No pairing. No yard setup. The truck agrees with the rest of the train as soon as it is powered.
Any truck can lead
Trucks can join the route, leave the formation or change positions. The train never depends on one lead vehicle.
Zero ongoing fees, any fleet size
No licence, subscription, base station, airtime or annual fee. Three trucks or thirty, each one reaches the same answer on its own.
Two contractors who have never met still agree.
Every LinQ truck runs on the same GPS clock, whoever owns it.
Proof from our own plant
17 hours.17 GPS outages.Still in step.
We ran a LinQ unit overnight with the antenna placed badly on purpose. The GPS signal came and went all night. Nobody watching the lights could have told you when.

Where a plow actually loses GPS
Overpasses and bridges
Heavy tree cover
Salt sheds and yards
Downtown canyons
None of these stop the lights, and none of them break the sync. When the signal drops, each truck keeps its own clock running and stays in step with the rest of the train.

Built to keep working
If one light stops, the rest keep going.
Every SWS snow plow package runs ArctiQ, a fail-safe design with no single point of failure. LinQ applies the same rule to time.
| Condition | Previous software | SWS ArctiQ with LinQ |
|---|---|---|
| Normal operation | All lights synchronized | All lights synchronized |
| Master failure | All lights stop | Receiver minibar or beacon takes over, and the lights stay synchronized |
| Communication line failure | Only the master works | Each receiver flashes independently, so visibility never drops |
| GPS signal lostLinQ | Each truck ran on its own clock | Each truck keeps its own clock running and stays in step with the train |

Questions fleets ask
What operators and fleet managers want to know.
Something not covered here? Call 1-877-357-0222 and ask for a LinQ specialist.
Do the trucks have to be paired or set up?
No. Power them and they agree. There is nothing to set up on the truck or in the yard, and no app for the operator to open.
What happens when a truck loses GPS?
It keeps its own time and stays in step. Our overnight test ran through 17 outages, the longest 35 minutes, and the lights never drifted enough to see. Under a bridge or in a salt shed, the module reports that it can no longer verify the time, then keeps flashing and keeps counting.
How long does sync take from a cold start?
The warning lights work the moment the truck is powered. The first GPS fix takes 30 to 60 seconds, and sync follows on its own. The operator does nothing.
Does LinQ track our vehicles?
No. The module reads the GPS time signal only. It does not record or report position, and it is not a vehicle tracking system.
Does it work with the lights already on our trucks?
Yes, on trucks with an SWS snow plow package. The rear bar, warning sticks and beacons keep the firmware they run today. The GPS module sits inside the new front minibar.
Is there a subscription or licence?
No. GPS is free to receive anywhere in the country. There is no base station, airtime, radio licence or annual fee.
Can any truck lead the train?
Yes. Any LinQ truck can lead, follow, join or leave. Nothing in the train depends on one vehicle.
