Fenix BC05R V2 USB-C Rechargeable Bike Light Bicycle Red Tail Light with EdisonBright Type-C Charging Cable Bundle

Great little light. Ultra light, easy to mount, super bright, and USB C rechargeable. Everything I could ask for in a light.

The USB-C charging aspect for me convenient as I usually carry a USB battery pack for my phone when I ride. After pulling the light off the charger when it's full, the light will last for many hours ( i tested it and stopped testing after 12 hours of continuous flash). However, the battery self-discharges over time - there were times that I used the light for only an hour and maybe 2 weeks later the battery was dead. However, a few minutes on the charger was enough to blink until I got home. The build quality is solid - I do not have any confidence issues there - only the battery. The clip mount holds the light very securely - I have it mounted to a rack trunk bag. Hope this helps.

Waterproof, durable, lightweight and the battery lasts forever in fast flash mode.

Very good light. Bright and works as described.

I really want to like this light. I am a big fan of Fenix products and have used many of their flashlights. This one for me is going to be a pass, though. The big issue is that the battery seems to drain while turned off in a relatively short amount of time.It's happened four times now where I go to bike to work in the morning and the light is completely dead, despite having double checked that the light was off when hanging my bike on its rack in my basement after a ride. This has happened in as little as 2 days of not using the light. At first I thought I was mistakenly leaving or turning it on, but I've been very good about checking that this isn't the case. My conclusion is that the battery continues to drain after it is turned off. Since this rechargeable, I'm not able to swap batteries when this happens and end up riding 13 miles on my morning urban commute without a light.I'm sadly outside of the return window and cannot return, so this light will be relegated to backup duty only in the event that my new primary light fails.

I had a bad luck with the first one, it didn't hold a change for longer than 3-4 hours. So, I just returned and exchanged it for another one. Wow, that was almost 4 months ago and I still didn't change it yet. Really nice, I will buy another one for my kid's bike.

The light is bright and easy to use, the only takeaway is the instructions. Not very clear.

I purchased for a multi day adventure race due to the great battery life and was not disappointed. Made it through the whole race without recharging.
