'I got this one wrong': As a running watch expert, I thought Garmin's LED flashlight was just a gimmick — but 4 years on, it's proven to be a top-tier smartwatch feature

(Image credit: Future) I hold my hands up. I got this one wrong. In 2022, when Garmin announced the headline feature for the Garmin Fenix 7X was an LED flashlight, I might have had a bit of a chuckle to myself about it.Since moving to multiple model sizes for its premium outdoor smartwatch, the largest ‘X’ models quickly came to represent the introduction of exciting, cutting-edge innovations that then start to filter down to the rest of the best Garmin watches. But I wasn;t convinced a multi-LED flashlight on the top of the watch case was something prospective Garmin watch owners should get excited about.Garmin claimed it would be a “game-changer for sport, adventure and daily life”. In the early weeks of testing the 7X, that wasn’t my experience. I’d quite quickly written it off as rather gimmicky. The question I kept on asking myself was; ‘why would I choose it over reaching for the pretty good LED flashlight I have on my phone?’It probably wasn’t until being out of that testing bubble of a month with the 7X and I started simply living with it, that my opinion began to change. I was using it more and more each week.

I was using it more and more each week.It started to become the flashlight I used when trying to quietly hunt out charging cables at night moving around my flat without turning on the main light and getting a telling-off. I didn’t need to be a further nuisance and look for my phone because I already had an exceptionally bright light on my wrist. Then it became the source of light on darker sections of my nighttime running routes or helping me to navigate my way back home from the gym. When I was dabbling in some DIY, it was less awkward to use than a phone to line up fixings.I began to appreciate that Garmin didn’t just slap on a flashlight because it could. It wanted to show how useful a wrist-based source of light could be. I now also had a flashlight I could set to strobe or match my running cadence to improve visibility. It could also switch from white to red light for a still bright, yet less intrusive way to illuminate what lay ahead and around me.Sign up for breaking news, reviews, opinion, top tech deals, and more.As Garmin moved to share the flashlight love to other watches in its range, it also continued to evolve its abilities to become smarter. Now when I went out for a run or walk after sunset, the watch would display a prompt to turn on the strobe mode to make sure I was thinking about staying seen as day turned into night. There’s a distress mode that when set up from the Garmin Connect app, can display emergency contact information on screen while flashing an SOS light pattern.It’s no big surprise that rival watchmakers thought it was a great idea too. Suunto, Coros, Amazfit and Polar now all have torch-toting smartwatches. (Image credit: Future / Michael Sawh)Are there any downsides of having a flashlight on a smartwatch? Well, it does mean creating more space on the watch case for it. That’s likely why so far it’s mainly been included on larger more rugged watches like the Suunto Vertical 2, Amazfit Cheetah 2 Pro and the Polar Street X, although Garmin has managed to plant it onto its slimmer Forerunner and Venu series watches.Another consideration is battery life. Running a flashlight while also using GPS or any other onboard watch sensors will contribute to that battery drain, but unless you’re planning to keep it switched on continuously for hours, I’m not sure the type of battery life drop you’ll experience is going to be anything to be massively worried about.How could it become even smarter? I think Garmin in particular has shown it can be more ingrained with your current environment or the time of day. Further integrating with safety features is an obvious one. Especially for anyone that goes on solo adventures. Could we get a UV mode or even be one strong enough to start a fire for that added outdoor appeal? As smartwatch makers focus on making brighter watch displays, should the same happen for the built-in flashlight?When it feels like there’s more of a focus on breaking new health tracking ground or cramming our lives and screens with more metrics , it’s easy to forget about some of the simpler gadgets that makes a smartwatch a useful thing to own. I’d now put the LED flashlight in the bracket of things I hope to see on any new smartwatch. We’ve not seen one on an Apple Watch Ultra model yet, so maybe that’s to come. I’ve definitely seen the light and it’s in the form of a feature I thought had gimmick written all over it.
