Prismolite Solar Road Studs – LED Active Road Delineators
PRISMOLITE Solar Studs are self-powered LED road delineators that harvest solar energy during daytime to deliver high-intensity active LED flashing or steady-light guidance at night and in poor visibility conditions. Unlike passive retroreflective studs, solar road studs are visible up to 800 metres, dramatically increasing driver alerting time. Ideal for deployment on smart highway projects, foggy mountain roads, accident-prone zones, and expressways under NHAI, NHIDCL, and smart city infrastructure programs.

FAQs
Frequently Asked Questions
Find answers to common questions about PRISMOLITE Solar Studs – Active LED Solar Road Studs for Smart Highway Safety, application standards, compliance, and performance.
Solar road studs are active devices that emit their own LED light, making them visible up to 800m compared to 150–200m for passive retroreflective studs. This dramatically improves driver alerting time in fog, rain, and darkness.
PRISMOLITE Solar Studs use high-efficiency lithium batteries charged via solar panel. A fully charged battery provides 72–96 hours of continuous LED operation, suitable for extended cloudy conditions.
Yes, solar road studs are highly effective in fog-prone sections as their active LED output penetrates fog far better than passive retroreflective devices, significantly improving road safety.
PRISMOLITE Solar Studs are engineered to withstand compressive loads of ≥20 tonnes, suitable for heavy vehicle traffic on national highways and expressways.
Minimal maintenance is required. The sealed unit is weatherproof (IP68 rated), and the solar panel and LED system are designed for 5+ years of operational life under normal road conditions.
