Designer Chukai's the Sound of Light is a three-in-one [emergency safety device](https://www.trendhunter.com/trends/switchbot-safety-alarm) that comes equipped with a [powerful LED light](https://www.trendhunter.com/trends/sk05-pro-blue-led), an ear-splitting whistle, a compass and a thermometer. Many hikers usually only carry one or two of the devices, but the chances of discovery and efficient extraction are only increased by the [combination of both sight and sound](https://www.trendhunter.com/trends/onurhan-demir) to spot and detect. The device uses an internal rotor that generates electricity for the LED light when air is blown through the contraption, serving as a noticeable beacon from afar. ## Trend Insights (Trend Hunter) - Score: 6.6/10 - Popularity: 96% | Activity: 93% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial - Top markets: North America, South America, Europe, Asia, Africa ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Lifestyle](https://www.trendhunter.com/lifestyle) > [Health](https://www.trendhunter.com/health) ## Key Themes ### What's Driving This Trend - **Multifunctional Emergency Devices:** The trend of combining multiple emergency safety features into one device provides convenience and enhanced safety for outdoor enthusiasts. - **Integration of Renewable Energy Sources:** The use of an internal rotor that generates electricity when air is blown through the device showcases the trend of integrating renewable energy sources into emergency products. - **Enhanced Visibility and Detection:** The inclusion of a powerful LED light and ear-splitting whistle caters to the trend of improving visibility and detection capabilities in emergency situations. ### Who This Affects Most - **Outdoor Recreation and Adventure:** The outdoor recreation and adventure industry can leverage multifunctional emergency devices to provide customers with comprehensive safety solutions. - **Renewable Energy:** The renewable energy industry can explore opportunities to collaborate with emergency device manufacturers and contribute to the development of innovative renewable energy-powered solutions. - **Safety and Security:** The safety and security industry can incorporate enhanced visibility and detection features into their product offerings for emergency preparedness and response. ## Related on Trend Hunter - [Compact Campsite EDC Tools](https://www.trendhunter.com/trends/portable-lamp-and-alarm.md) - [Outdoor Adventurer Product Lineups](https://www.trendhunter.com/trends/outdoor-adventurer.md) - [Multipurpose Camping Lights](https://www.trendhunter.com/trends/camping-lights.md) - [Multifunctional Camper Lantern Devices](https://www.trendhunter.com/trends/caheo-camping-lantern.md) - [Emergency Audio Speaker Hubs](https://www.trendhunter.com/trends/crankspeaker.md) - [Intelligent Accessible Light Designs](https://www.trendhunter.com/trends/lamptok-light.md) - [Emergency Distress Signals](https://www.trendhunter.com/trends/sos-light-app.md) - [Illuminating Miniature Multifunctional Gadgets](https://www.trendhunter.com/trends/maglight-mini.md) - [Adaptable Campsite Illuminators](https://www.trendhunter.com/trends/beyondop-led-camping-lantern.md)
