Last spring, I purchased an LED anchor replacement bulb from Imtra. I spent a lot of time trying to determine what base design I had in the Hella 2492 fixture, and I thought I had got it right.
When we tried to swap the bulb out with the OEM incandescent, the bayonet socket on the bulb had offset pins, and the fixture called for in-series pins. I went to Imtra to get the right bulb, but they do not make it in cool white, so they kindly allowed me to return the bulb for a refund, even though the bulb base was dented during the attempted install and the bulb had to be scrapped.

Speakers and Compasses
With regard to the marine stereo kits (PS, August 2012), I found I needed about six feet from the compass to the stereo speakers on our Compac 23/II to avoid interference. Compac provided me with a partial drop board that I mounted an Aquameter compass in so it would be centered in the middle of the boat. I ran tests with the compass and the speakers in our living room where I could get the distances and measure the deviation without stuff on the boat causing magnetic distortions. A shielded speaker magnet is surely to be a help.
