Maybe one suggestion; add an instruction for the use of the MEC light. There is nothing mentioning it now. I think they will tend to use it as a flashlight to help them see. They may not realize that it can also be used to be seen, especially with this light which has a blink mode, which would help attract attention at night.

Perhaps under the "Make yourself seen" instruction, add something like "at night, turn on light to blink mode and keep it on outside your cloths or the bag if you are wearing it. Since there is no mirror in the kit, delete that instruction and use the light instruction instead. Proper use of a mirror to signal an aircraft/helicopter is probably too advanced for this level. The blinking light IMO is better.
