What color flare does the MK-124 night signal emit?

• A. Red
• B. Orange
• C. White
• D. Green

Answer: (A)

At night, distress signals use color to convey an urgent message, and red is the color universally used to indicate a call for help. The MK-124 night signal is a red flare designed to burn bright and be visible at sea after dark, so it clearly signals distress and requests assistance. The other colors aren’t the standard night distress signal: white is typically used for illumination or signaling location, orange relates to day signals or other non-distress signals, and green isn’t the recognized night distress color. So a red MK-124 flare is the correct choice for indicating a need for rescue at night.
