Smartstud ® solar. The Smartstud ® Solar is a unique self-illuminated road marker that switches on at night. Each marker is comprised of a solar panel and four high-intensity LEDs. The marker presents an appealing design for both rural and urban applications, such as lighting of access ways, culvert markings or company grounds.
These days, we can find solar panels, also known as photovoltaic cells, just about everywhere. They're on the roofs of our homes, bringing down the cost of electricity. They're even on top of a few cars. In 2019, Toyota began testing outfitting the Prius Prime with solar battery panels on its roof, hood and rear hatch door.
The solar system of solar powered marker lights is conducive for reducing environmental impact and saving costs. With more than 15 years of factory experience, led road reflectors produced by our company owns competitive price and offers more choice to global traffic road safety market and trustworthy partners all over the world.

Item No: B01XX Solar Delineator Markers. Key Feature: 1. Easy installation 2. No maintenance cost 3. Absolutely Safe design (Embedded design, only 3-5mm above the road surface, much lower than standard raised pavement markers. Raised pavement marker is over 20MM above the road surface, too high and too dangerous to the cyclist.
In some parts of the United Kingdom the standard design life is 40 years for new bitumen and concrete pavement. Maintenance is considered in the whole life cost of the road with service at 10, 20 and 30 year milestones. Roads can be and are designed for a variety of lives (8-, 15-, 30-, and 60-year designs).
The advantages of our raised pavement markers on motorway are ASTM D4280 & EN 1463-1 standard; high reflectivity, fade resistance; special groove design to improve reflectivity and compression resistance; lowest cost, good adhesive ability and easy to be installed, making our raised pavement marker popular on global market.
As you are driving you’ll see reflective road studs marking the road. These are also called reflective studs and cat’s eyes, because as you approach them they look like a pair of cat’s eyes on the road, and they originated in the United Kingdom back in 1933.
