Knog Blinder 1 Twin Pack with red anodized faceplate. I have 6/8 unopened packs left. I'm on campus.

These lights are easy to clip around your seat/handle bar stem, the USB connector is built into the strap. The lights are super bright, I can go a ~week+ without recharge on the blinker mode (it has a few modes + constant on). I use them around campus, people see me coming.

Its a good quality product: silicone strap, solid USB connector, splash (I'd say waterproof), anodized faceplate and super bright LED.

From the Manufacturer:

High-powered surface-mount LED and the lithium polymer with its inbuilt USB recharge is held in sweetly by a flexible silicone strap and clip. Tool-less attachment for handlebars and frames of 22-32mm. Visible at over 500 meters.
