After reading ppls posts concerning mast top anchor lights, I have
decided that they are nearly useless so I will not bother to fix mine.
Instead, I want a light with super-bright LEDs that emits only
outward (I dont want it to put light on the deck). I dont want an
electrical connection to my boat so it should have batteries. Since
an extended cruise would require many d-cells or many 6 V batteries,
it should have rechargeable NiCd or gelcell batteries to be recharged
from the boats 12V system during the day. It should have a state of
charge indicator. Of course, it should be BRIGHT when seen from any
reasonable distance, be waterproof, shock resistant, etc. I expect to
mount it on a halyard suspended in the foretriangle. I do not see
such a light anywhere. So, making one shouldnt be too difficult, as
the electronics are easy. Would other ppl be interested in such a
light?

Yes, he photocell is a very good idea and easy to implement. As far
as connecting to your boat 12V supply, I really want to get away from
using a dangling wire connection like that. I tried that once and it
was a pain. Maybe it could be done in an easier way though.
