There is an intersection in my city in Germany where the lights and signs puzzle me.

I usually want to turn left there. What I suppose should be relevant for me is the sign marked with the red arrow (the text reads: Those turning left should position themselves like that) and the traffic light marked with the green arrow. It is impossible to see at my phone camera's resolution, but from up close, it shows a bicycle and an arrow to the left, like this one:
At first I thought that I am supposed to start ahead when that light turns green, cross the street in front of the viewpoint (FS), then turn as shown on the sign and wait there until I can cross the street to the left of the viewpoint (LS). But the light only turns green for a very short time, maybe 10 to 15 seconds. And during this time, the signal is green for cars coming from the left on the FS, so it is impossible to cross.
Then I thought that I maybe should cross first while the cars' traffic light on the LS is green, then position myself as shown on the sign. But as soon as I have crossed, the angle is all wrong and it is impossible to see the bicycle traffic light any more. If I am directly in front of it, I have to angle my neck up to see it, and that way cannot see much of the rest of the situation on the crossing. If I turn left and go a little bit back, as shown on the sign, the viewing angle is so shallow that I can see the surface of all three colors from the side, and all seem equally lighted, so it is impossible to tell which one is on.
So I now completely disregard that light, cross with the cars' light the FS, then turn left and use the pedestrian's light to cross the LS.
What is the actual meaning of the traffic light, and how is it supposed to be read?
