Woog is a bicycle light meant to be attached on wheel spokes like a regular wheel reflector. LEDs light up on both sides of Woog and the regime (constant/flashing/other) can be changed by pressing one button on the device through different options. Woog can be either turned on by holding down the button for a second or it may be activated by an accelerometer. When the bike is at stop for more than a minute, the light turns itself off automatically. The color of the light may either be separate for each product or it can be programmed through a mini-USB port (when RGB LEDs are used + the user can also program his/her own lighting regimes) which is also used for recharging.
There would also be an opportunity to use the rotary motion the light goes through and generate current that can thereby used to recharge the device.
