Versatile, Low-Maintenace &

Long-Lasting Outdoor Solar Lighting

Today's roadways have more safety devices than at any other time in history. However, even with these devices, there are more fatalities than ever. Overhead lighting, pavement markings, and chevron signs are all great ways to enhance rural road safety, but there are now even more innovative and effective ways to enhance drivers' safety, experience and reaction time: SolaRight's wireless lighting products, models YHDD1 and YHYS.
Made from the high-quality materials and using SolaRight’s POWRtech technology, these Internally Illuminated Recessed/Raised Pavement Markers are designed to save lives for many years to come with little to no maintenance.


Dark roadways account for a large percentage of accidents and fatalities. Coupled with less-than-ideal conditions, it can be a recipe for disaster. Narrow bridges, two-lane roads, four-lane transitions to two-lane roads and interchange gores are all examples of problem areas on darkened roads that can benefit from SolaRight'sIIRPMs.

 SolaRight's Internally Illuminated Raised and Recessed Pavement Markers (IIRPMs) are ideal on darkened roadways because they:

  • Require no wiring or electricity- powered by the sun

  • Work well not only for night driving, but overcast, rain, fog and other adverse weather conditions

  • Act as an additional alert for drivers without being distracting

  • Work well for traffic channelization and as a traffic calming device

  • Offer visibility up to ½ mile away

  • Help delineate lane geometry and curvature of the road

  • Aid drivers in seeing unexpected road hazards and

  • Can be more practical than overhead lighting. 

Because some drivers are not acquainted with the roads, it’s very important to place the lights carefully. Traffic engineers and the SolaRight professionals can help you determine proper road placement.

Some of the more common uses of our products on darkened roads include:

  • Curved roads

  • Preview upcoming obstructions

  • Illuminate Stop Signs or other traffic signs and STOP Lines

  • Narrow bridges

  • Four-Lane Transitions to Two-Lane

  • Two-Lane Roadways

  • Dangerous intersections and

  • Areas that are hazardous in dark or inclement weather.

Not Uncommon on Curved,
Darkened Roads

About 75 percent of all fatal crashes occur in rural areas, and more than 70 percent are on two-lane secondary highways, many of which are local roads.

Although accidents can occur anywhere, darkened roads are even more dangerous. When curves are combined with inclement weather, these roads can be extremely hazardous. These conditions, coupled with a driver who may be unfamiliar with the road, can be disastrous. SolaRight's Internally Illuminated Recessed and Raised Pavement Markers (IIRPMs) work in conjunction to help show the geometry of the road and aid in safe stopping distance while not distracting the driver.
