Here is a new bike light with stealth concept.
The light is fixed to the handlebar of a bike by an elastic o-ring or a piece of o band cut from an old bicycle inner tube. There is a 3.5mm jack at the side of the product for charging the battery and an on-off switch at the back.
The circuit uses 3 leds, one for standby and others 1w white leds for lighting. This is an intelligent lighting system with the details you can read from our first bike light article
