I asked in a Radforum for suggestions and so came to this luminaire.
Continuous light, flashing light, out - that's it, no 17 different flash modes
is switched by pressing further
The light is quite small with a diameter similar to that of a 2 Euro piece.
The switch in the center occupies a large part of the illuminated area.
In remaining ring lights 3 LED's, appealing bright and clearly visible.
Nevertheless, I consider it my purposes sufficient (Small, light, emergency lights, can be made while driving on / off.)
Note:
I drive whenever it does not go on the road!
For those in the rush hour in the dark with cycling to work want to ask you bought a decent, big taillight. No matter where the switch is located and how much outweighs the light
