blue Hella KL7 12V Flash Light Beacon

Rare blue Hella KL 7 flash light beacon in used condition. I tested the lamp with 12 Volt and it is working. For your info, the grey cable is ground. The blue lens is a bit aged but without damaged. The chrome is a bit aged but without dents. The badge is marked with “Hella KL7 12V B1003 DIN made in Germany”. The base is made of metal and without dents and the base diameter is 14,5 cm. The total height is about 20 cm and the weight is 1130g. Hard to get in this nice condition.
