Which item is used to attract attention with sunlight reflection?

• A. Flares purpose
• B. Strobe light purpose
• C. Air horn purpose
• D. Signaling mirror purpose

Answer: (A)

Reflected sunlight is a reliable daylight signaling method, and a signaling mirror is built for that purpose. The mirror uses a polished surface aimed toward the sun; when you flash it toward a distant observer, a bright, brief beam of sunlight is directed to attract attention. This works without batteries or fuel and can be seen from long distances in clear daylight, making it an effective emergency signal on the water. Flares do create bright light, but they generate light themselves rather than reflecting sunlight, and they’re limited in duration and carry additional hazards. A strobe light offers artificial light and needs a power source, so it isn’t about sunlight reflection. An air horn signals with sound rather than light and is more useful for nearby signals. So the item designed to attract attention specifically through sunlight reflection is the signaling mirror.
