Case Studies

At SWS, we’re constantly advancing the benchmark for performance by introducing new technology that will help us build the brightest and most reliable beacons, minibars, traffic arrows and directors. This allows us to provide the best quality amber lighting and related products in the industry.

We help municipalities and businesses like yours identify their challenges with warning light technology, and offer an entire family of LED products to address your needs. We will custom build to your specifications, whether you require one piece of equipment or an entire lighting package with multiple colour combinations and functions.

Here are some specific examples of our experience:

Enhancing the Visibility of Snowplows


Snowplows have previously been mandated to require similar lighting to construction and public works vehicles, which included amber and blue strobe and rotator beacons and minor perimeter lighting.  This resulted in trucks that were not as readily identifiable from other public works vehicles, and rear-end collisions on freeways and higher speed roads. 

Truck Mounted Modular Traffic Arrow


Quebec and Eastern Canada were updating their flashing arrow requirements for short and long term construction on public roads, which required the use of truck mounted and trailer mounted arrows with specific dimensional layouts.  The new requirements involved the use of a round modular style layout while previously approved SWS traffic arrows use extruded aluminum housing with rectangular LED panels.

Replacement of Strobe Technology


Zenon strobe systems had been the go to technology for high brightness warning lights for decades, since the 1960’s.  They were a very high output low cost system that didn’t require too many components to produce a flashing pattern that was discernable over a large distance.  Unfortunately, the components that make the system are not very rugged, produce large amounts of EMI, draw quite a bit of current (amps), and contain material like lead and mercury.

Two colours in one warning light


Vehicles had typically been utilizing a warning light that produced a certain colour of light depending upon the colour of the outer lens or dome.  Police, Fire, and Ambulances began using two colours to help with visibility of the vehicle as well as identification of the type of vehicle, but this was still done with coloured lenses or domes or the use of two different coloured lights.  This was the result of the use of halogen or Zenon strobe systems being capable of producing only “white” light.

Traffic Director with more features


Traffic directors are usually a single long system comprised of 4 or more light elements that are “flashed” in a sequence as to convey the intent of the desired direction for traffic to divert.  The issue is that they tended to be mounted high on the back of a vehicle to maximize visibility, but could block the center high mounted stop light (CHMSL or third brake light).  Lowering the traffic director would minimize its effectiveness, so some users had to choose between having the CHMSL visible or maximizing the effectiveness of the traffic director.
