Hella KLJ 70M magnetic beacon blue lens 12V

12V Hella KLJ 70 M magnetic beacon lamp with blue lens in used condition with a problem. I connected a bulb to the cable, but the bulb didn't light up. The rotating mechanism works perfectly, the blue lens has some sticky grime on it but which can be removed and everything else is in good condition. The blue base is without dents and stamped with “Hella, 2RL 003 130-00, Made in Germany, Glühlampe H1 12V 55W DIN, K8605, CH1 1280 06, A, 71341, T.P.F.S. A31”. The blue lens is dirty, without cracks and stamped with “CH1 1280 03, CH1 1280 04”. The magnet and rubber are in very good condition. The mount clip is complete, working very well and marked with “Hella KBA 90031”. This made in Germany beacon is Hella KL(J)70 with special magnet and roof clip.
