*KNOG* plug front (black)　

PLUG series from KNOG, the Australian bike accessory brand.
Very subtle and compact design, also they literally look like some sort of plug.
Since this light is given with exchangeable silicon straps, it gives you multiple choices of handle bars to attach too.
The huge button switch on the back allows users to quickly turn on/off the light, and change modes even with gloves.
It even has a maximum of 250 lumens; enough for daily use.
There is a USB plug behind the huge button in the backside to charge its battery.

*USB cable not included*
