Very bright and convincing at first glance

The taillight was delivered very quickly. Many Thanks.
The packaging is simple, but adequate.
The main focus was the light. Inserted the batteries, lamp plugged back together, and the first test run.
She is really very very bright. The first pressure on the pressure switch the "Disco" -Blinkmodus is (according 60h. Manufacturer) triggered. Here both LEDs flash alternately back and forth quickly, which sometimes flashes one way or another 2-3x itself and then the shift to other LED. Then suddenly an LED lights up, gently faded out - then the other well - they both light up briefly, and hide from the program starts all over again - nice and varied.
The second keystroke allows only one LED light continuously (30h lt. Manufacturers), the next print shine both of (15h lt. Manufacturer's instructions). At the last keystroke the lamp is off.
The holder is shown and is plugged onto the terminal (terminal enables you to connect to bags or clothing). After mounting on the seat post follows. A rubber ring is also included with. Tool is none required.
When long-term test remains to be seen whether the holder can prove their worth. So far, I'm really confident and can safely recommend.
