How to Use Your Flashlight's SOS and Strobe Functions: Proper Usage for Saving Lives in Emergencies, Disasters, and Power Outages
Many flashlight models are equipped with SOS and strobe functions, but many owners may not know how to use them correctly. While these functions can save lives if used properly during distress, power outages, or disasters, incorrect use can also impede rescue operations.
This article provides a comprehensive guide to the correct use of flashlight SOS and strobe functions. We will detail everything from rescue signals in distress, ensuring safety during power outages, and emergency applications, along with recommended models from Aestiquo.
Difference between SOS Function and Strobe Function
| Function | Flashing Pattern | Main Use | Features |
|---|---|---|---|
| SOS Mode | 3 short, 3 long, 3 short (Morse code) | Distress, emergency rescue request | Internationally recognized distress signal |
| Strobe Mode | Rapid flashing (fixed interval) | Location signaling, ensuring visibility | Easily visible from long distances |
| Flashing Mode | Slow flashing (fixed interval) | Ensuring visibility in daily life | Power-saving, running, cycling |
Correct Use of SOS Mode
3 short (・・・) → 3 long (ーーー) → 3 short (・・・)
SOS mode flashes in this internationally recognized Morse code pattern. All rescue agencies, including helicopters, rescue teams, and ships, recognize this pattern as a "call for help."
When to Use SOS Mode
Use SOS mode only in true emergencies where self-rescue or rescue is difficult. Unnecessary SOS signals can trigger futile deployments of rescue teams, delaying responses to those who genuinely need help.
| When to Use | When Not to Use |
|---|---|
| Lost or stranded in mountains | Lost but can return on your own |
| Injured or unwell and unable to move | Tired but able to walk |
| Water accident, near drowning | For testing or practice purposes |
| Fire, trapped in a building | For everyday visibility |
| Unable to call for help by yourself | When you can contact by smartphone |
Emergency Scenarios: How to Use SOS and Strobe Functions
First, contact 119 (emergency services), the police (110), or mountain rescue via your smartphone. If your phone has no signal, activate SOS mode in an open area (ridge, summit, wide slope) and shine it towards the direction of potential helicopters or rescue teams. To conserve battery, send signals by turning the light on and off periodically.
Steps: ① Move to an open area → ② Call 119/110 → ③ If phone fails, activate SOS mode → ④ Use in conjunction with a whistle → ⑤ Turn on/off periodically to save battery
In water accidents in the sea, rivers, or lakes, signaling your position with strobe mode is the top priority. Strobe flashing on the water surface is highly visible to ships and helicopters from a distance. A flashlight with IPX7 waterproof rating will maintain its function even if dropped in water. Attaching it to a life jacket will automatically signal your position in a water emergency.
If trapped inside a building due to fire or earthquake, you can signal your location to rescue teams by shining the strobe mode light outwards through windows or gaps. If smoke is heavy, stay low and use the light to find exits and emergency doors while evacuating.
During a power outage, use normal steady light mode or flashing mode, not SOS mode. SOS mode should only be used in true emergencies. During a power outage, a COB work light can illuminate a room, and strobe mode can be used for outdoor position confirmation and evacuation guidance.

Disaster Preparedness: Preparing a Flashlight with SOS Function
Always Keep in Your Disaster Bag
A flashlight equipped with SOS and strobe functions is an essential item for your disaster preparedness bag. Check its charge every three months (e.g., on Disaster Prevention Day, year-end, Golden Week) to ensure it's always ready for use. Include a whistle with the flashlight in your disaster bag so you can send rescue signals with both sound and light.
Share Usage with Family
Ensure all family members know how to use the SOS and strobe functions in an emergency by sharing the instructions beforehand. Explaining it to children and the elderly is especially important. Also, convey the rule: "Do not use it except in emergencies."
