small weaknesses in detail

I have this set now for more than three years (beginning of 2012, then for 82.50) and am quite happy with it. so far no water damage (yes, I'm sometimes in the pouring rain down), but I had to replace the holder of the headlight! although she made a high-quality impression, it has badly worn over time, and the light wobbled back and forth. There are now also better support with thumbscrew ("Busch & Müller Universal handlebar holder"; not at Amazon).

+ Light intensity of the headlight
+ Using AA Batteries & Charging with AC adapter (both included)
+ Mounting of the rear light

- Fit cover front light
- Special battery taillight

the front light is really terrific: the dark one sees himself very well and responsive hardly be dazzled! one sees only the scattered light from the mirror surface and not looking directly at the LED. I think that is corrosive to most other lamps ...
super is that the lamp with batteries work (standard Mignon (AA)) and can even be charged directly with the supplied AC adapter.
only the flap really sits not 100%, that's too bad! but I've no water damage (not even the rear light) can find.

As mentioned in other reviews it is a horror that for the rear light such batteries must be used: Line N Lady LR1 ... after the second batteries ended up contact after I had the contacts of the lamp handle slightly bent ... Otherwise, I think the taillight well. I think enough luminosity and holds a battery for a while.
the sensors are a cool gimmick, wherein said motion sensor is very sensitive. the lights are either permanently (a red status LED will flash) or in sensor mode (green status LED) at least 4 minutes, when a sensor starts. eg: dark -> light on; Bicycle parked -> after 4 min: light; Continue -> Light on; bright -> after 4 minutes of light.
attachment I also very well done. I have (;-) but more secure today?) opted for the theft variant in which the holder is not secured with rubber but a steel band and screws - so that it is now easier to directly take the saddle! the lamp can be additionally attached to the bracket with a Torx screw, which is also intended to serve the protection against theft.

All in all, a good lamp set that is worth its price largely.
