SolarLite Series General Information

Making do with sub-standard visibility on the road is a recipe for disaster, collisions and in the worst case scenario, fatalities.

Conventional “cat’s eye” retro-reflective studs have been around for decades and in that time, their performance has barely changed. They still rely on the effectiveness of the vehicle’s headlight beam to provide enough light at the right angle to reflect some of that light back at the driver to delineate the road ahead. At best, that headlight beam normally extends to about 90m.

SolarLite active road studs don’t have that same dependency. They don’t rely on the headlight beam of the vehicle at all. Instead, they actively deliver light output directly in the natural line of sight of the driver from high brightness LEDs in the stud. These LED road studs are powered by solar energy captured from natural sunlight by the in-built solar panel and stored in the stud’s internal battery. As a result of this active light output, they deliver 10 x greater visibility of the road layout ahead than the traditional retro-reflective road markings, giving drivers up to 900m visibility.

And this is proven to make a significant difference, reducing night-time road accidents by over 70%.

Let’s put that into perspective. A motorist driving at a speed of 100km/h (62mph) will see 90m of delineation from retro-reflective studs. This provides around 3.2 seconds to react to changes in the road ahead. With active road studs providing up to 900m visibility, reaction time available to the motorist is over 30 seconds. This provides plenty of time to take in and process information about possible hazards ahead and adjust your driving accordingly without needing to slam on the brakes.

Even in poor conditions (rain, fog or surface spray) where traditional retro-reflective studs and road markings are less visible, SolarLite studs continue to shine brightly, guiding you safely.

SolarLite road studs are more robust and durable than traditional road studs, meaning they’ve a lower overall lifetime cost than a retro-reflective road stud and better longevity.

Just a few hours of daylight will provide enough battery power to last days – more than enough to ensure the system operates all year round, whatever the weather and wherever the location in the world.

The SolarLite studs are fully Type Approved by the United Kingdom Department for Transport.

Whilst initially conceived for use on roads, their low profile makes the SolarLite active road studs perfect for use in a wide variety of additional applications such as pedestrian and cycle paths, on crosswalks, level crossings and railway platforms.

IRS2 General Information

The innovative and flexible design of the IRS2 intelligent road studs provides drivers with advance awareness of the road ahead, giving them more time to react accordingly.

Suitable for a wide range of applications from dynamic lane marking, tunnel delineation to pedestrian crossing systems, the revolutionary IRS2 intelligent road studs are effective in all lighting conditions, making them a clear choice when it comes to improving driver awareness and behaviour on our roads and offering a demonstrable impact on road safety.

A hardwired product, the IRS2 intelligent road studs are driven via mains power into an integrated controller unit that enables the product to be configured precisely to the user’s requirement, whether that be for timed use, or for providing constant or flashing light output.

When used in conjunction with road capacity and expansion schemes, dynamic lane marking using our IRS2 studs can increase highway capacity and reduce congestion.

The studs have been used to successfully delineate the Hindhead Tunnel in Surrey to guide motorists through the tunnel safely and allow switchable delineation between normal and contraflow running, resulting in quicker, smoother journey times for road users.

They have also been deployed at Sheriffhall roundabout in Edinburgh, where they are used to increase driver awareness and improve lane discipline on and off the roundabout.
The bi-directional studs can be switched between uni and bi-directional settings and can be specified with different colours in each direction.
