I had exactly the same problem, recently. Chandler and importer (both in NL) were very helpful and gave me immediately a replacement. This one only produces minor static. Of course this should be totally absent. But I can live with it. After this experience I found this thread and I copied them to the the chandler and importer. Very useful and many thanks to the contributors.

I am afraid that the tricolour LED equivalent could cause far more static because of higher power consumption and I will not replace the 25W bulb.

The brand is well known and the anchorlight LED costs €73. Also the VHF is a well known brand.
