The Procyon isn't just a seat post light. Its small size and secure clamp mean you can attach it to a backpack strap when you're walking or running, or to a helmet for that extra high-up visibility. The flash mode is great for daytime use, while the steady modes help at night. And because it charges via USB, you can top it up at your desk or on the go. For a compact light, it packs a lot of functionality into a 26-gram package.
Charging takes approximately 1-2 hours via USB.
The quick-release bracket slides onto the seat post, backpack strap, or helmet strap, and locks into place.
Yes, the flash mode is designed to attract attention even in daylight, making it ideal for daytime running lights.






This light is really bright and easy to mount. I use it every day in the city and feel much safer.
I like the different modes and the build quality is solid. But I wish the battery lasted a bit longer on the highest setting. I have to charge it every few days with my commute.
I've had drivers tell me they can see me from far away. The strobe mode is really eye-catching. I've been using it for a few months now and it still works perfectly. The USB charging is convenient too.
It does the job but the mount feels a bit flimsy. I've had it pop off once on a bumpy road. Also, the button is a bit small to operate with gloves.
For the price, this is an amazing light. It's bright, compact, and the battery lasts a good while. The clips are versatile. I've bought two more for my family.
I appreciate the different brightness settings. It's easy to charge with the USB cable. It's been rained on a few times and no issues. Good purchase.
Worked fine for a few weeks, then it just wouldn't turn on. Tried charging but nothing. Waste of money.
I run at night and this light gives me peace of mind. The flashing mode is very visible. It's lightweight and doesn't bounce around. I highly recommend it to any runner or cyclist.
