I am not SAR. Personally I like my flash lites to be simple. It's not that I can't figure out how to use them, but I find having to cycle through multiple modes to be annoying.

Additionally, I don't think SOS should be built into a regular flash lite. As mentioned earlier a normal person would ignore a strobe, but may respond to SOS. If a SOS feature is an available setting on a flash lite, I feel it would become overused by the general public and start to lose it's meaning.
