This LED bicycle safety light has one large Chip-On-Board (COB) LED light that is a dual red and white light. It has 5 different modes to cycle through, and so can be used both as the front white light or also as the red tail light. It is weather proof so you can cycle in the rain, when you need to be visible the most. It will run from 2 hours 45 minutes, up to 5 hours 15 minutes on one charge, depending on what setting it is on, then it is just a matter of plugging it into any USB port with the supplied cable to charge it - no need to replace and use wasteful batteries!
This light comes with a stretchable band that wraps around the handle bars and rear reflector or seat bar, making the size fitting flexible.
Just press the power button to cycle through the different modes, and push and hold the power button to turn it off.
