How long does the MK-127 last?

• A. About 60 seconds
• B. Burns for about 36 seconds
• C. About 20 seconds
• D. About 90 seconds

Answer: (B)

MK-127 is a short-duration signaling device used to create a visible signal for marking a location or signaling for help. It is designed to burn for a limited time, providing a bright emission for about 36 seconds. This duration gives a clear, noticeable signal without excessive heat or weight, and mirrors how the device is specified for use. The other times would either cut the signal too quickly to be reliably seen or go beyond what the device is built to safely deliver. If longer signaling is needed, you’d deploy additional devices rather than extending a single discharge.
