Improve Driver Performance in Lowlight & Hazardous Conditions

Whether from state highways, interstates or other thoroughfares, off ramps can be a high risk for drivers especially at night. To better call attention to the geometry of the road, SolaRight offers products to help illuminate these areas. SolaRight's IIRPMs work in many areas in the traffic industry, serving many various purposes, including traffic calming, lane channelization and aiding in sight distance. Because our products are available in many colors, it’s very versatile:

  • Off-Ramps
  • On-Ramps
  • Frontage Roads
  • Access Roads
  • Jersey Barriers
  • Gores
  • Safety Signs and
  • Guardrails.

Improved lighting can greatly increase the safety of on- and off-ramps.

Provide Tracking Information & Guidance to the Driver

Lane delineation and channelization can be extremely important to drivers who may be entering or exiting a road via on and off-ramps. SolaRight's Internally Illuminated Raised and Recessed Pavement Markers (IIRPMs) can greatly improve driver response time, positive guidance and convey the message of upcoming traffic changes without distracting the driver.

Raised off-ramp lighting is useful when a guardrail or other longitudinal barrier is present along with a roadway or ramp or for helping identify object markers. 



Off-Ramp Lighting Promotes Short and Long Range Information

Not only do SolaRight's lighting solutions work well in conveying a short-range scenario, but they also work well in helping guide drivers over a longer stretch of road. This low-lighting is not distracting to the driver, but it does help improve the driver’s sensory perception, sight distance, traffic calming and prepare for upcoming changes in geometry.

Works Well on Its Own or As Part of A System

 SolaRight's IIRPMs work well to show driver hazards, but they can also greatly enhance existing solutions, such as reflective paint or signage. In cases where paint or signage may not be enough, these lights can improve vision and give positive guidance to drivers.

In inclement weather conditions, the SolaRight lights can be particularly beneficial. The reduced visibility associated with the effects of weather, such as rain, snow, and fog, makes driving difficult and sometimes dangerous. SolaRight's discreet lighting is visible up to ½ mile away, but they will not hinder visibility or the driver’s reaction time.
