Bought 3 lamps

Now I have already installed 3 lights. The 1st about 2 years ago to see if the what is good. I'm surprised you make very good light and the sensor is no longer needed you also and issue, you do everything on its own. Only with the connection I had to try a little, what, where goes, because the bike I had no plug and the LED headlight was not included wiring diagram. If one should face the same problem, the cable from the lamp must for Dynamo and the plug contacts are intended for the rear light. Now with the 2 new lights I installed today I did not have to think twice because the bikes plug on the cables for the rear lamp had.
