German cycle route signposting, an apology!

Over the years I have complained about the German habit of putting small square shields with an arrow and a bike logo at right angles to the direction of travel as intermediate signposts on cycle routes. It is not always possible to decide which route these signs refer to or which direction you are following. However we recently cycled across a local forest in the dark and it was pitch black. It was very spooky with odd souls (walkers) and dogs with glowing eyes appearing suddenly out of the gloom.  We have decent lighting and could follow the path, but was it the right one? We were both very pleased to see the bike logo and arrow signs shining brightly in our headlamps at junctions.
