Ideal for fall, winter and night.
The processing is stable, only the push for the front turn signal is somewhat delicate, had the attachment after a few weeks passed (Was that a bolt? If so, is not countered.), So that I, the holder (or thrust) had to be tied with cable ties.
The turn signals require good brand batteries, Sanyo eg held almost half a year, front and rear, while cheap batteries had to be recharged almost weekly new (it was so annoying).
Inserting the batteries and synchronize the turn signals in the cold lead to some frustration, was even a battery have a loose connection, but otherwise it went smoothly.
The brightness of the indicators is really good, also to be seen in the morning, superfluous day. The main front light is good for the market, for the performance, but does not serve rather to illuminate the road or of things for the cyclist, the rear light interacts with three LED also a bit weak.
I went with that thing in all weathers, there were no technical failures, no rust on the battery contact points or softening of plastic etc.
Some controls from Ordnungsamt and police astonished faces came out and positive feedback Highway Code or not, it is out of date and you drive much safer with these indicators, especially when turning especially left turns.
I really felt so safe, noticed that motorists me better perceived and on indicator Although a little with astonishment reacted but it took them true and serious, because I now have to buy a new bike, these indicators may not be missing ( and yet not even the neon safety vest).
Conclusion: security, better being perceived and futuristic style - everything, these indicators, but do not forget: For optimal transmission of the road, the front light is not enough.
