For anyone that doesn't somehow already know, SOS is pretty simple to learn

It's just three threes of dots dashes dots.

. . . - - - . . .

Sentences finish with a full stop (or period if you're American), so you can remember it's the dots last (and therefore first)

Hopefully you never need to use it, but better to know it and not need it than the alternative

To add onto that: dots are short, dashes are long. So if you're using a flashlight, or something else, it would be:

short, short, short, long, long, long, short, short, short

Then include a small pause (1-3 seconds) once you've sent the SOS before repeating. You want to continuously repeat this for as long as you can until you know someone's received your message.
