For bikes registered in Germany the backwards facing blinkers have to be offset 12 cm from the center line (innermost edges) to either side and be mounted at the same height. Minimum height above the pavement is 35 cm (measured without the rider to the lower edge of the blinker). The blinkers have to be yellow in colour and flash at 1,5 Hz +/- 0,5 Hz (90 flashes +/- 30 flashes per minute).
There are however special regulations for vehicles registered in other countries that I'm not sure about. You'd have to check with a local TÜV office, the local vehicle registration office (KFZ Zulassungsstelle) or the police.
