Morse Code SOS Light (Real Method Step-by-Step)

In this quick guide, I will describe to you exactly how to signal morse code SOS lights with no prior experience.

First off, why should you trust me? I have been studying morse code for about a year, and I know almost everything you need to know about morse code signals – especially emergency morse code signals such as SOS. Emergency signals are easy and essential, so that is a great place to start!

Learning many different forms of emergency signals is great practice if you get into an emergency situation. 

There were many instances where the morse code saved people’s lives. As an example, a few weeks ago, a man crashed his car while drunk, and a flame bursted out within seconds.

Continuing, he had to get immediate help – so he decided to do morse code with his car horn and was lucky to have survived. Hopefully you will survive in a situation like his.

Without further ado, let’s cover morse code SOS lights.

The Morse Code SOS Light

First, you want to tap on the light or sound device three times (dot); each time is about a a 0.25-second quick blink to signal S. Then, you want to pause for a little and hold the key down for about 1-second three times for the O (dash). Finally, repeat the S again by tapping lightly for 0.25-seconds three times.

The SOS morse code light is quite simple, and all you have to be good at is counting and oning and offing your light. You can also be creative with your lights; if you don’t have a lamp, use a flashlight, a phone, or even a horn.

Now, as a precaution, make you are very careful with your message, one accidental key, and your whole message is messed up. A good rule of thumb is to wait about a second before going on to the next letter when sending the visual distress signal.

If you want, you can save this image, below on all your device as a reference. I also recommend you learn and practice morse code if you want to communicate with others effectively in an emergency situation.

Other Emergency Morse Code Signals

There are several other morse code signals that will go great with the SOS signal. Sometimes, being more specific helps in almost any situation. Things like CQD (come quick danger) or hospital are great things to learn. As stated above, it is a good rule of thumb to wait for a second in each letter.

The first on the list is “come quick danger” or “CQD”, one of the first morse code signals ever invented. 

To signal, do a 1-second flash, then a 0.25-second flash, then another 1-second flash and 0.25-second flash. Then, two 1-second flashes, following a 0.25-second flash and another 1-second flash. Finally, do a 1-second flash and then two 0.25-second flashes.

The second of the list in the hospital. First, do four 0.25-second flashes for the H, three 1 second flashes for the O, three 0.25 second flashes for the S, and a 0.25-second flash following two 1-second flashes and another 0.25-second flash for the P.

Continuing, we have two 0.25-second flashes for the I, a 1-second flash for the T, then a 0.25-second flash following a 1-second flash for the A, and finally a 0.25-second flash following a 1-second flash, and then two more 0.25-second flashes for the L.


In this quick guide, you learned the morse code SOS light flashes, along with CQD and hospital. I hope you will never have to use any light signal. 

However, if you do, I hope you at least remember how to do the simple SOS light. It is three short 0.25-second taps, along with three 1-second taps, and finally another three short 0.25-second taps.
