Highlight in LED technology

I have tried a few reflectors, but which can be seen best of all. It is much easier to see than an ordinary LED rear light be spread beam. The parking light function funzt after only a few turns of the wheel of the hub dynamo, no battery, a capacitor is charged and is also in the state of full light.
As the wheel is turned, the capacitor can be discharged by means of a small Knöpfchens - off the light! Protects the wheel before the attention of thieves. In addition, the rear light is not necessarily noticeable in its construction.
We recommend!
