This bicycle light can grow easily. A pair of cables leading directly to the (hub) dynamo, there shall be the copper wires and closes this on to the connector system. Another (short) cable pair leads to the taillight. The headlights work for me after installation (approximately 20 minutes) from the start. Something I'm unhappy with the switch, which is installed behind a rubber cover. Thus it can not be so easily operated ("fiddly"). By means of the switch is only switched on and off the parking lights. Otherwise the lamp leads continuous light, which is ok for me because I also daytime driving light. I had, however, expected that I can therefore turn the light completely. The lighting is excellent. I've never had such a bright light on the bicycle. A light cone looks ahead and is felt 3 times brighter than conventional halogen light. Some light is radiated also in the vicinity. The lamp is rather small and visually esp. On a trekking bike inconspicuously. Given the price, a clear recommendation. For the fiddly switch I draw from a point.
