With Firefly lights, you can now use turn signals on your bike. Signal your intentions from the front and rear to make your commute safer. Remote sold separately. AUTOMATIC BRAKE LIGHTS Obtain an add-on remote and unlock the auto brake lights. Lights up your Firefly when you are slowing down. TEAM SYNC Introducing the first-ever syncing bike lights. Each Firefly is able to connect to one another, allowing them to flash in the same pattern across multiple riders. Our research found that this allows groups to be more identifiable by cars and trucks in the dark. CONNECTS TO YOUR HELMET Each Firefly can sync to your Lumos helmet. Sync your flash pattern, turn signals, and auto-brake lights. UNLIMITED PAIRING Connect as many lights to as many helmets and riders as you want. SMARTPHONE CONTROL Download the RideLumos App to unlock countless features. IP7x WATER RESISTANT We designed the light to be charged wirelessly, allowing the body to be waterproof. Qi WIRELESS CHARGING Charges with any Qi wireless chargers or use the Lumos Charging Cradle. Level Up Your Commute with Lumos Lumos Firefly Lumos Firefly Mini Firefly Charging Cradle Firefly Quad Charging Mat Turn Signal Mount Lumos Remote Firefly Universal Mount Review: Awesome set of lights - So these are awesome. They work with my Lumos matrix helmet. I like the fact I can turn off the helmet and all the lights turn on. I wish that was the same for turning them on. You have to turn each one on individually. These were easy to install and get going. Be sure to read everything because there are features that are available that are not easily found. I wish there was some sort of plastic mount that could house two of these on the front or rear of the bike as a pair. Including a charger of some sort would also be beneficial. I am still waiting to see how much battery life I will get out of these. I am enjoying them and find that they are made exceptionally well. The magnetic mounts are super strong! Review: Fantastic for my use. Maybe not for yours. - Love these with a few caveats. The form factor is nice, they are bright enough, blinker function works very well, app is alright. The battery life kinda sucks and the wireless charging is inconvenient. Just use usb c and id be so much happier. Charging from dead takes a while and they don’t give any feedback about their state of charge. For my cargo bike I cannot find a better light with blinker functionality. If you have a regular bike and don’t need the blinker function I’d probably look elsewhere. ## Features - Synchronized Flashing: Increase visibility and safety with Lumos Firefly's synced lights that create a larger visibility footprint, making it easier for motorists to spot and gauge your size and distance. - Turn Signals & Automatic Brake Lights: Activate turn signals using a Lumos Remote (sold separately) or smart devices, while built-in brake lights (activated via Lumos Remote) warn drivers when you slow down, preventing collisions. - Flexible Placement: Each Firefly light features red, white, and yellow LEDs, allowing it to function as a front, rear, or turn signal light.

The magnetic mounts are super strong! ### ⭐⭐⭐⭐⭐ Fantastic for my use. Maybe not for yours. *by J***. on March 23, 2026* Love these with a few caveats. The form factor is nice, they are bright enough, blinker function works very well, app is alright. The battery life kinda sucks and the wireless charging is inconvenient. Just use usb c and id be so much happier. Charging from dead takes a while and they don’t give any feedback about their state of charge. For my cargo bike I cannot find a better light with blinker functionality. If you have a regular bike and don’t need the blinker function I’d probably look elsewhere. ### ⭐⭐⭐⭐⭐ Bright, versatile, and super high quality. *by B***. on February 4, 2025* You really can't get a better quad light system, but you're going to have to pay for it... The versatility of these makes it worth it in the long run. The magnetism is really strong, but they include a little optional clip on for each light to further shore the light to the bases if you're concerned and you're doing heavy mounttain biking. ## Frequently Bought Together - Lumos Firefly Smart Bike Light System - Sync Front & Rear LED Light | Custom Brightness, Flash Pattern, Day/Night Mode | Turn Signals | Brake Lights | Night Riding Bicycle Accessories for Men & Women - Lumos Remote with Charging Cable - Lumos Firefly Charging Cradle --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/535070889-firefly-smart-bike-light-system-sync-front-and-rear-led](https://www.desertcart.co.uk/products/535070889-firefly-smart-bike-light-system-sync-front-and-rear-led) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
