143MM Round Solar-Powered Road Studs
The 143MM Round Solar-Powered Road Studs are composed of traffic signal LEDs, die-cast aluminum, solar panels, lithium batteries, and other materials. They are filled with transparent soft rubber adhesive, making them solid throughout, so rainwater cannot penetrate the product, ensuring an absolutely sealed and waterproof design; The front surface features a slip-resistant finish, and the LEDs are mounted using a through-hole method, providing greater compression resistance than surface-mount LEDs. Additionally, the traffic signal LEDs are designed for outdoor use, offering high brightness, high-temperature resistance, and an extended service life.
143MM Round Solar-Powered Road Studs refer to a type of traffic signal indicator used at intersections with traffic lights. They display red and green signals and are mounted on the road surface, primarily on crosswalks or on the traffic island in front of the first crosswalk.

125mm Solar Round Buried Traffic Light
The 143 mm solar-powered circular ground-mounted luminaire is an active luminous safety warning product for road traffic applications. Solar Round Road Stud 143MM features a diameter of Φ143 mm, a height of approximately 50 mm, and is designed for ground installation—level with the road surface. Solar Round Road Stud 143MM operates on solar power, requiring no external wiring, and is suitable for road contours, crosswalks, and intersection warnings. Solar Round Road Stud 143MM provides high-brightness illumination in nighttime, rainy, or foggy conditions, thereby enhancing road visibility. (See the figure below)
Product Features of the 143 mm Circular Solar Ground-Mounted Lamp
Active nighttime illumination warning system: features high-brightness LED light sources powered by solar panels, automatically activating in low-light environments; supports continuous illumination or flashing modes, with optional synchronized linkage with traffic lights. Solar Round Road Stud 143MM emits light during nighttime, rainy, or foggy conditions, addressing the limitation of conventional reflective road studs—where reflective performance fails in rainy weather—thereby enhancing road delineation and warning visibility at crosswalks.
Road contours and boundary markings: Clearly delineate the road edges, center lines, curves, ramps, and bridge edges, enabling drivers to quickly identify the road layout, anticipate changes in road alignment, and reduce the risk of accidents on curves and cliff-edge road sections.
Pedestrian Crossing Safety Warning Sign (Integrated Version): Installed at the stop line of a pedestrian crossing, this device can synchronize with pedestrian signal lights; during a red light phase, Solar Round Road Stud 143MM flashes in sync to alert motor vehicles to slow down and yield to pedestrians, while also reminding pedestrians to be cautious of oncoming vehicles, thereby enhancing pedestrian crossing safety at intersections.
Heavy-duty pavement signage: embedded installation with a housing flush with the pavement surface; resistant to vehicle rolling loads; suitable for motor vehicle lanes and heavy-duty intersections; provides long-term pavement signage durability and is resistant to damage from vehicle tires and snow removal equipment.
Wireless standalone operation: powered by solar energy without the need to install cables; features a built-in energy storage battery that ensures continuous operation during cloudy or rainy weather, thereby simplifying installation wiring and reducing power supply costs.
All-weather adaptability: IP68 full-sealed waterproof design ensures reliable operation in flooded or heavy rainfall conditions; the cast aluminum housing provides resistance to pressure and impact, making Solar Round Road Stud 143MM suitable for harsh outdoor environments characterized by extreme temperature variations and dust exposure.
The core pain points addressed by the 143 mm circular solar ground-mounted lamp for customers
Addressing the failure issue of conventional reflective road studs during rainy or nighttime conditions
An active-emitting LED light source that provides self-contained illumination, eliminating reliance on vehicle lighting. Solar Round Road Stud 143MM ensures long-distance visibility even in rainy or foggy conditions, guaranteeing reliable road detection in adverse weather.
Addressing the pain points of high costs associated with external cabling installation and the susceptibility of pipelines to damage.
It is solar-powered, eliminating the need for wiring or cable routing in walls, which significantly reduces construction material and labor costs; each unit operates independently, so the failure of a single unit does not affect the entire system, and maintenance is straightforward.
Address the issue of protruding rail spikes on the road surface, which are prone to damage from snowplows or vehicle collisions.
The device features flush-mounted embedding, fully integrated into the road surface with its top surface level with the pavement, enabling Solar Round Road Stud 143MM to withstand snowplow operations; it also employs a die-cast aluminum alloy housing that offers high compressive strength, ensuring resistance to damage even under repeated loading from heavy-duty vehicles.
Addressing the critical pain point of high water ingress failure rates in outdoor environments characterized by humidity and standing water.
Equipped with an IP68 full-immersion sealing design, this product can withstand prolonged immersion in standing water, making Solar Round Road Stud 143MM suitable for areas prone to heavy rainfall or low-lying waterlogged sections. It offers superior moisture and water resistance, thereby reducing on-site rework rates.
Product Installation
This marking refers to the line used to guide the stakes, ensuring they remain at a consistent level.
First, drill holes at the predetermined positions for the smart crosswalk; the hole depth may be 55 mm, with a diameter of 145 mm (the slot holes only need to be slightly larger than the guide studs; there are no strict requirements for this). Simply drill circular holes for installing the lighting fixtures.
At both ends of the crosswalk, attach a white line along both sides of the crosswalk. Place the ground-mounted studs flush along this white line, ensuring that all studs lie on the same line and remain level.
Once the product has been positioned along this reference flat line, achieve balance. First, position the rail spikes, then secure them with cement.
Batch Aging
Usage Precautions
This product features an aluminum housing; heavy pressure should be strictly avoided to prevent damage to the housing. The device must be powered on only under the supervision of a qualified professional; do not disassemble or assemble the luminaire without authorization.
