300mm-Yellow-Flashing-Two-Aspects-Solar-Powered-Warning-Lights
The 300MM-Yellow-Flashing-two-aspects-Solar-Powered-Warning-Lights are a type of traffic signal typically installed on both sides of the road or on the crossbar of traffic lights. They are commonly used in areas where vulnerable groups (such as students and patients) are present along roadways (e.g., schools, hospitals). They can be installed using either a pole-mounted or cantilever-mounted configuration and are powered by solar energy. The light’s input voltage is 3.7V, while the solar panel’s input voltage is 6V. Due to its low operating voltage, the solar panel can function as long as there is light, converting light energy into electrical energy to charge the battery—meaning the solar panel can charge the battery even during the day when there is no direct sunlight.

300MM solar dual yellow flasher
The Model 300 solar-powered dual-yellow-flashing lamp assembly features a luminous diameter of Φ300 mm and employs a dual-layer configuration with two yellow-flashing lamp surfaces (upper and lower). The top surface integrates a solar photovoltaic panel. This device is an independently powered LED traffic warning signal lamp that requires no external mains power; instead, 300MM solar dual yellow flasher relies on solar energy storage for power supply. The yellow lamp flashes continuously, serving as a road warning signal to prompt vehicles to reduce speed, observe the surroundings, and proceed with caution. (See the figure below)
Features of the Model 300 Solar Yellow Flash Dual-Lamp Product
Dual-synchronous yellow flash:Two Φ300mm yellow LED light discs, positioned above and below, flash synchronously, providing continuous yellow warning illumination to alert drivers of potential hazards ahead on the road section. This serves as a road warning signal light and does not impose traffic control measures.
Long-range visual warning:The bright yellow LED, combined with an optical lens, provides strong light transmission, ensuring clear visibility even in rainy or foggy conditions, with an effective warning range exceeding 500 meters.
Self-charging via solar energy:The top-mounted monocrystalline solar panel captures sunlight during the day, converting light energy into electrical energy to charge the built-in energy storage battery, eliminating the need for external mains power or wiring.
Continuous Battery Life Feature:Once fully charged, 300MM solar dual yellow flasher can operate with continuous flashing during multiple consecutive rainy days, ensuring that warnings remain uninterrupted even in adverse weather conditions.
IP53 protection:The entire unit is waterproof and dustproof, capable of withstanding rainwater erosion and dust ingress, making 300MM solar dual yellow flasher suitable for outdoor environments.
Wide-temperature operational stability:It operates stably in ambient temperatures ranging from-20 °C to +65 °C, making 300MM solar dual yellow flasher suitable for use in both extremely hot and extremely cold climates.
The Type 300 solar yellow flash dual-lamp solution addresses the core pain points of customers.
In the absence of mains power on-site, the cost and duration of cable installation are significantly increased.
This solar-powered standalone power solution eliminates the need to excavate road surfaces or lay cables, thereby eliminating associated costs for pipelines, distribution boxes, and power connection approvals. Once the equipment arrives, the poles can be erected and secured with clamps for rapid installation, significantly shortening the construction timeline. This system is particularly well-suited for locations without access to electricity—such as rural road intersections, mountainous curved roads, and temporary construction zones.
Poor visibility during nighttime or rainy weather leads to a higher incidence of accidents at intersections, and there is a lack of continuous warning measures.
Dual-light panel with dual yellow flashing indicators provides doubled warning effectiveness; the high-brightness yellow LEDs offer strong penetration, ensuring clear visibility from long distances in foggy conditions, at dusk, and during nighttime. Equipped with an integrated light sensor, the system automatically activates flashing mode when 300MM solar dual yellow flasher gets dark and enters a sleep mode for charging during daylight hours—requiring no manual operation. This ensures continuous reminders for drivers to slow down and observe their surroundings, thereby reducing the risk of collisions at level intersections, village entrances, and industrial plant access points.
Traditional electrical warning lights fail when power is cut off, suffer from unstable power supply, and require cumbersome maintenance.
Equipped with a built-in energy storage battery, 300MM solar dual yellow flasher can operate continuously during multiple consecutive rainy days when fully charged; it features battery overcharge and over-discharge protection to extend battery lifespan; the LED light source has a service life of up to 100,000 hours, and the housing is resistant to UV-induced aging, ensuring a low failure rate during prolonged outdoor operation with minimal subsequent maintenance requirements.
When equipment is installed outdoors, exposure to rainwater, dust, and extreme temperature conditions can easily damage the signal lights.
The entire unit features an IP53 protection rating, ensuring waterproof and dustproof performance; the PC engineering plastic housing is impact-resistant and UV-resistant; the operating temperature range is-20 °C to +65 °C, enabling stable operation in extreme heat, severe cold, and rainy or snowy environments, making 300MM solar dual yellow flasher suitable for outdoor applications in the vast majority of domestic regions.

"O":close
"II": 24-hour illumination
Product Installation (Vertical Installation Example)
method of erection:
1. First, fix the elongated bracket to the back side of the solar panel using two screws;
2. Then, fix the small bracket in the center of the pre-installed long bracket using two screws;
3. Next, leave a screw on each end, then unscrew the nut on the screw;
4. Place the flat end of the "L" -shaped bracket onto the screw rod, aligning it with the holes and slots; then, slide the solar panel bracket onto the screw rod, followed by the washer and nut; finally, tighten the nut. Lastly, connect the solar panel connector to the luminaire connector.
(as shown in the figure)
5. Shade cap: Install it on the upper part of the lamp; fold the three triangular plates into a curved shape to fit over the lamp, then use screws to fasten them into the corresponding holes.
6. Drill two holes in the lamp post; align these holes with the hole positions of the signal L-bracket; insert a suitable screw through the lamp post, slide the L-shaped bracket over the screw, and secure it with a nut. (As shown in the figure)
300MM solar dual yellow flasher Usage Precautions
This product features an aluminum casing; heavy pressure should be strictly avoided to prevent damage to the casing. The device must be powered on only under the supervision of a qualified professional; do not disassemble or assemble the luminaire without authorization.
