What I also really great find:
The N version for use with hub dynamo has a fixed cable for connection to the Dynamo. In addition, two terminals and an included two-wire cable to connect the rear light. The trick is that it lets you off at the front light both lamps with the switch.
Even two cable lugs and heat shrink were there, if you want to assemble a professional (me enough the clamping device for the wires).
Something erfeuliches: I could see the light on my old lamp holder mount (the connection seems to be standardized). So even less Schrauberei for attaching the lamp.
The parking light function ("plus") I do not want to miss. It just feels safer at the traffic lights, crossing the road, etc. The capacitor holds the charge even when the power really long. Ie immediately light when the lamp anknipst again after a few hours!
Am also glad that I do not have me wrangle with batteries, but with this lamp in combination with a hub dynamo have a robust lighting system on the bicycle.
A very solid lamp that is really worth every penny.
