Frequently Asked Questions

Q: How long does the solar LED warning light need to charge before first use?

A: Before using the solar warning beacon for the first time, place it face-up in direct sunlight for a minimum of 4 hours. This ensures the battery is adequately charged to deliver reliable overnight flashing performance.

Q: Will this solar warning light work in cloudy or overcast weather?

A: Yes. While direct sunlight provides the fastest charge, the built-in solar cell can still collect energy on cloudy days. A fully charged battery (achieved in approximately 2–3 days of good sunlight) will keep the beacon flashing through periods of reduced sunlight.

Q: Is any wiring or external power source required for this LED warning beacon?

A: No wiring or external electricity is needed. The unit is entirely solar-powered with a built-in rechargeable battery. Simply flip the bottom switch to ON and let the light sensor manage automatic operation.

Q: What surfaces or structures can this solar warning light be used on?

A: This versatile beacon is suitable for a wide range of applications including construction site equipment, tower cranes, fences, chimneys, bridges, high-rise buildings, port terminals, harbors, and road traffic zones. Its lightweight, portable design makes it easy to position virtually anywhere.
