In the dark, the night end of the MK-124 is identifiable by ___________ on the night end.

The night end of the MK-124 is identifiable by a distinctive color, specifically an orange band. The design of the MK-124 flare is intentionally made so that during low visibility situations, such as at night, the distinct color can easily be recognized by the crew. This feature is critical for ensuring the safety of personnel in emergency situations where visual signals are necessary for locating and identifying flares quickly.
