Fingertip-sized, IPX8 waterproof, dual-output, and powered by CREE, Luminus LEDs — built for everyday carry.
Check on Kickstarter

Bullet3 is a 3cm micro flashlight built for everyday carry — delivering real brightness, IPX8 waterproof protection, and pro-grade LED performance in a body you’ll barely notice. Always on your keys. Always ready when you need it.




Smaller than your fingertip and lighter than most keys, Bullet3 is designed to stay on your keychain without adding bulk. You won’t feel it in your pocket — and you’ll forget it’s even there, until you need it.



Bullet3 comes in multiple lighting versions, each built for real situations — cool white for clarity and outdoor use, warm white for softer everyday lighting, and red light for preserving night vision.
Each version features dual output levels — low for extended use and high for instant visibility, whenever you need it.
Powered by premium LED emitters from CREE and Luminus, it delivers cleaner light, better efficiency, and more consistent performance — all in something this small.






With IPX8 waterproof protection, Bullet3 keeps working in rain, splashes, and unpredictable environments — because real life doesn’t happen in perfect conditions.


Instead of charging ports and cables, Bullet3 runs on replaceable button cells, so it’s ready the moment you need it. No cables, no downtime — just replace and go.



Available in titanium, brass, and aluminum, Bullet3 is built to match your everyday carry — whether you prefer premium, classic, or ultra-light.



On your keys, in your bag, or in your car, Bullet3 is ready for both everyday moments and unexpected situations — from unlocking a door at night to finding something in your bag or making quick checks in the dark. Small moments, but they happen every day.




Since 2018, YSMART has been building compact tools designed for everyday carry. From our first keychain flashlight to multiple generations of upgrades — battery, rechargeable, and even wireless charging — we’ve continued to explore what a small light can become.
Now, we’ve gone back to what matters most
Bullet3 is our smallest flashlight yet — and in many ways, the most essential. Stripped down to the core. Focused on what you actually need. Small enough to carry every day, without thinking.



Shipping fees will be charged after the campaign ends, during the post-campaign survey. Rates are based on package weight and destination, and will be finalized at that time. All prices are inclusive — no additional VAT, duties, or taxes will be charged upon delivery.
