We bought a second anchor light in Mexico and hung it from the backstay. It
had a photovoltaic switch which turned it on at night. It was built by a
cruiser from parts available at Radio Schack and a glass salt shaker. It
saved us from having to dinghy back to the boat from wherever we were every
night. Masthead anchor lights are great but on a clear night and up so high
they look like a star. Finding your boat at night in a crowded anchorage can
be a problem. We put reflective tape on the mast. Shining a flashlight on
the boats made it easy to find ours. On Kerosene anchor lights, I don't
thinnk they are legal as they can't be seen from the required distance. Walt
