Eisemann Bosch RKLE 90 24V blue light beacon

Rare Eisemann Bosch RKLE 90 24V blue flash light beacon in used condition. I tested the light with 12V and only the bulb is burning. The spinning function is not working. The chrome ring is without dents but with age. The light itself is without dents. The light has still the original Eisemann sticker. The lens is nice and without damages but it has some scratches at the top and it is marked with "B1007". The base diameter is 14,5 cm, the total height is 20 cm and the base is 5 cm height. The Eisemann RKLE 90 light was made in Germany by Bosch.
