The MK-124 day/night pyrotechnic device produces ________ colored smoke for daytime conditions and ___________ colored flare as a night signal.

The MK-124 pyrotechnic device is specifically designed for signaling both day and night conditions, making it a critical tool for search and rescue operations. During daytime, the device emits orange smoke, which is highly visible against the backdrop of the sky and can be effectively used to attract attention. This choice of color is particularly effective in daytime signaling scenarios where bright, contrasting colors are necessary for visibility.

At night, the MK-124 produces a red flare that lights up the surroundings and serves as an excellent visual distress signal. Red is a universally recognized color for emergencies and is easily discernible in dark conditions, making it particularly useful for signaling rescue units or nearby vessels at night.

This dual functionality—producing orange smoke for daytime use and a bright red flare for nighttime signaling—makes the MK-124 a versatile and essential piece of equipment for boat crews, ensuring safety and communication in various visibility conditions.
