The company that I intend to use is <A target="_blank" HREF=http://www.orcagreen.com/>http://www.orcagreen.com/</A> their web site does not have an anchor light at the moment, but I have been talking to them and they intend to market an appropriate LED bulb for the existing cheap anchor light housings in the spring at abt $80
Got mine from Duncans in Glasgow but similar ones are available from Compass and Force 4. I took off the cigar lighter plug and put on a couple of clips as my batteries are closer to the forehatch than my plug.
It was reliable, economical on power but a bit expensive to buy.. no one rammed us so I guess it works!
davis do ananchor light, its not led but it is very low draw, i believe the bulb is rated at about the same life as an led, nice thing about it is turns on and off automatically............keith
If you have a 'Wilkinsons' store in your town, they do an LED torch which also has an 'all round' adjustable bit for five UKP including batteries. It says it is weather resistant. I bought a couple for the boat just before Xmas.
I have used in the past one of those tubelight inspection lights, the draw on those is minute and the light given off is enough to keep you awake on a dark night, only problem it was not waterproof so it soon packed up, but I am sure this could soon be waterproofed with a bit of sekaflex etc I think they are about £5 or £6 but not more than £10 any motor factors. I am thinking of mounting one on top of the mast permanently they are about 12" long.
