If you're seeking reliable, customizable, and factory-direct signal lights, you've arrived at the right place.

Since 2003, WelandSignal has specialized in the original equipment manufacturing (OEM) of solar marine lanterns, LED obstruction lights, vessel signal lights, and airport guidance systems.

We firmly believe that product quality begins at the source. To this end, we manufacture all key components — PCBA, solar panels, battery packs — in-house. Our engineers have full control over the design, testing, and production of our products, which are designed using imported components and automated production lines.

Our journey in developing GPS-synced lighting solutions began in 2011. Since then, our products have been adopted by maritime authorities and telecom tower projects, and shipped to over 80 countries.We currently offer a suite of products, including solar airport lights, GSM monitoring, AIS lanterns, base stations, and testing tools — all designed for remote control without the need for on-site intervention.Our monitoring system integrates with existing global platforms or operates independently. It also supports customization and remote upgrades.For special environments, we provide bird-repellent lights that combine LED with ultrasonic technology.

Every solution is customizable, reliable, and made for tough outdoor use.

Every light undergoes rigorous testing to ensure quality and reliability.

These tests include waterproofing, resistance to high and low temperatures, salt fog, drops, and light intensity.

AC/DC models: These products come with a 5-year warranty and a lifespan of over 20 years.

Solar models: They come with a 3-year warranty and use 4000-cycle LiFePO4 batteries that last for 15+ years.
