What is the stated visual range for the signaling device?

• A. 1-2 miles
• B. 2-5 miles
• C. 5-10 miles
• D. 10-20 miles

Answer: (B)

Visual range is the distance at which a signaling device can be seen and recognized by an observer with normal eyesight under standard conditions. For this device, the stated range is about two to five miles, meaning it should be clearly visible to a lookout up to roughly two to five miles away under typical conditions. This range reflects the device’s brightness and contrast as specified by the manufacturer and regulatory guidance. Outside of this range, visibility isn’t guaranteed because atmospheric conditions, background clutter, and the observer’s angle can all reduce clarity. In practice, you plan for the lower end of the range in less favorable conditions and use additional signaling if you need to reach beyond that distance.
