At the terminals of the rear light reaches a minimum movement to the contact of the flat tabs to the PCB to destroy. The interconnect is not introduced from the soldering side of the soldering of the flat tongue but from the opposite side. Then via a via the soldering of the spade tag on a tiny surface. One can choose where that goes first broken. Either damaged the solder pin the flat tongue even during installation the via or the via goes at the slightest movement of the push-on connector broken or the tiny soldering surface separates from the board.
As long as the board is not new layouted, I am also a little room for improvement. Have connected by means of two short wires the soldering tags of multiple plug pins with the closest solder tails of the following components so that the taillight connectors work now.

Bought for 12 euros two additional headlamps with Radshop Kneuertz.
The internal electronics have been redesigned.
The flat plug pins of the rear light connectors are clearly more massive soldered to the board.
Both headlights were also after intensive bending and shaking on the connections no contact problems.
On a bike, the lead-out cable down to the dynamo and the horizontally extending piece Bowden the front V-Brake came to the cultivation in the way. By means of screwing on the housing and smaller file just settled a small slit at the side filing in the rear bracket so that the cable could be out of the housing side.
Room for improvement:
In the measurements of the headlights, I noticed that the headlamp uses only one half-wave of the AC voltage of the dynamo for themselves and the taillight. This perhaps explains the flicker at a very low speed. The pole sensitivity, so the mechanical resistance caused to the hub dynamo, which could perhaps strengthen somewhat. But no information about whether to make the more expensive Spotlight better.
For value for money I raise my rating from 1 to 4 stars.
