Aluminum Solar Road Stud | 30-Ton Super Load-Bearing, IP68 Waterproof Active Warning Road Marker
Traditional reflective road studs rely entirely on the illumination of vehicle headlights. In the event of heavy fog, heavy rain, or blind spots at curves, its very difficult for drivers to react in time.
Solar road stud lights are active luminous traffic guidance devices powered by solar energy. During the day, they automatically absorb sunlight, convert it into electricity, and store it. At night or in rainy and foggy weather, they light up automatically. They can effectively outline the road contour, alert drivers to upcoming curves, pedestrian crossings, and dangerous road sections, breaking free from the limitations of vehicle headlights and providing a much longer visual distance.
YFFY-SRSA9 Heavy Duty Solar Road Studs adopt a dual warning mechanism of “active luminescence + passive reflection”. They do not just reflect light; they actively emit bright light at night, directly increasing the safe visual distance to over 600 meters, buying golden hazard-avoidance time for drivers.
Core Advantages of Solar Cat Eyes
1. Active + Passive Dual Warning:
The solar road stud lights feature built-in high-brightness LEDs that flash actively or stay constant, paired with high-retroreflectivity optical lenses. This delivers a powerful visual impact with zero blind spots, regardless of whether vehicle headlights are shining on them.
2. 30-Ton+ Extreme Compression Resistance:
Utilizing a high-strength die-cast aluminum shell with a perfect streamlined anti-impact structural design, it is wear-resistant and corrosion-resistant, easily withstanding the crushing force of heavy-duty trucks.
3. High-Brightness LED Beads:
Fitted with large-sized φ8 super bright, long-lifetime LEDs (2 for single side / 4 for double sides), providing extremely strong light penetration.
4. Ultra-Long Battery Life & Lifespan:
Charging for 12 hours provides over 120 hours of continuous operation. The entire unit has a design lifespan of up to 5 years, is maintenance-free, saving you time and effort.
5. All-Weather IP68 Top Waterproofing:
Seamless sealing technology ensures stable performance even under heavy rain, water accumulation, or brief submersion. Its operating temperature ranges from -20℃ to 80℃.

Wide Application of Aluminum Solar Road Stud
YFFY’s solar road markers are perfect for safety warning applications on urban roads, highways, and private sectors:
-
Highways and Urban Arterial Roads: Especially on sharp curves, steep slopes, foggy road sections, and tunnel entrances.
-
Crosswalks and School Zones: Reminding passing vehicles to slow down and yield, ensuring pedestrian safety.
-
Industrial Parks and Logistics Centers: Outlining heavy-duty truck lanes and the edges of loading/unloading platforms.
-
Private Estates and Scenic Spots: Guide lighting for villa courtyards, private driveways, scenic pathways, docks, and parking lots.

Installation Guide for Aluminum Solar Road Stud
We offer two solar road markers styles: Flat Bottom and With Shank (50mm), to meet different road paving requirements.
1. Road Surface Preparation and Positioning: Pre-construction Preparation
Determine the installation location, clean the road surface of dust, gravel, and standing water, and ensure the surface is dry and clean. If using the shank style, use a professional drilling machine to drill mounting holes matching the diameter and depth beforehand.
2. Mixing and Applying Glue: Core Bonding Step
Use specialized epoxy resin glue or asphalt glue. Apply the glue evenly to the bottom of the solar LED road stud light (if there is a shank, apply glue inside the hole and on the shank simultaneously).
3. Pressing & Securing: Positioning and Alignment
Press the road stud firmly into the installation position (or insert it into the hole), rotate it slightly to ensure the glue overflows fully, and adjust the reflective surface of the solar road stud to directly face the oncoming traffic.
4. Cleaning and Curing: Waiting Before Traffic Clearance
Use a scraper to clean off any excess glue around the road stud. Before the glue is completely cured (usually 4-6 hours, depending on the temperature), please set up isolation cones to prevent vehicles from running over them prematurely.

Packaging & Logistics Information Of Aluminum Solar Road Stud

Frequently Asked Questions

Q1. How Long Does It Take To Fully Charge The YFFY-SRSA9 Aluminum Solar Road Stud, And How Long Can It Work On A Full Charge?
A: Under standard sunlight conditions (100,000 lux), it takes about 12 hours to fully charge. Once fully charged, both the flashing and constant light modes can run continuously for more than 120 hours (over 5 days), ensuring stable operation even during consecutive rainy or cloudy days.
Q2. What Is The Difference Between The Flat Bottom Style And The Shank Style, And How Should I Choose?
A: The Flat Bottom style is ideal for flat, hard surfaces such as concrete pavements, pedestrian streets, or indoor parking lots where drilling is not preferred. The aluminum solar road stud With Shank (50mm) style features anchoring pins that insert directly into pre-drilled holes in the road, which provides superior stability against heavy shearing forces. It is highly recommended for asphalt roads, highways, and heavy-duty traffic areas.
Q3. Can These Heavy Duty Solar Road Studs Withstand Heavy Trucks and Freight Vehicles?
A: Yes, absolutely. The YFFY-SRSA9 is built with a high-strength die-cast aluminum alloy casing and features a streamlined, impact-resistant design. With a certified compression load-bearing capacity of over 300kN (more than 30 tons), it can easily withstand repeated rolling from heavy-duty cargo trucks and container vehicles without cracking.
Q4. How Does The Light-Control Sensor Work On This Solar Road Stud Lights?
A: The road studs feature integrated intelligent auto-light control (ambient sensor operating at 300-900 lux). It automatically detects ambient light levels—turning the LEDs on as night falls or when heavy fog/storms reduce visibility, and automatically shutting off at dawn to conserve power and recharge.
