If you have solar panels but not the sensing function above, simply place a 12V NC relay on the anchor light with the coil going to the solar panel input into the regulator. This assumes you are using nominal 12V panels - higher ones need a different voltage relay.

When the panels are active, the relay opens and turns off the anchor light. When the panel voltage drops below 12V, the relay closes and the anchor light turns on.

I wired ours this way for many years before we got a new light with a sensor built in.

The problem with this is the power consumption of the relay coil can be greater than the power saved by turning of the LEDs.
You could use a latching relay but they are difficult to get.

Re: LED Anchor Light

I realize this is too late for the original post, but for some reason I still can't keep quiet.

I'm surprised that no one has mentioned Lopolight.

We have a combined tricolor and anchor light. We got it some years back while racing offshore races, but when we started to sell our racer/cruiser we kind of stripped her of the cool things.

Our current boat (100% cruising) had a led tricolor/anchor light that was installed to the old casing in Papeete (if I remember right or at least somewhere on the Pacific) but we exchanged it because this Lopolight is very compact and watertight. I know it's a bit on the expensive side, but when it comes to navigation and anchor lights we just want to have the best.

Re: LED Anchor Light

These days I can't see not having an LED tri-color and anchor light. The power savings is just too great. There are a number of others who have posted problems with Lopolights LED nav lights. They don't seem to be any better than the ones that are much less. High price in marine gear does not always equate to high quality or performance.

Before LEDs, the main attraction (to me, at least) of a tricolor was the power savings of one bulb instead of two or three. With LEDs, that's pretty much a non-issue. My current boat does not have a tricolor. I'm changing the deck-level nav lights over to LEDs but not adding a tricolor. I understand the arguments of added visibility and spray protection from having the light at the top of the mast, but I'd rather have the easier access of the deck-level lights.

The visibility of a mast head light is so superior to deck level lights. Even if I am powering, I use the mast head tri offshore, as I'd rather be seen than perfectly legal. It is surprising how quickly you loose deck level lights on a sailboat offshore and how far away you can still pickup mast head lights. We sailed up the east coast this summer with a friend whose mast head light was out. They were often only a mile or less away and we would loose them in seas at night.

Re: LED Anchor Light

I've got a Bebi anchor light that I'm very satisfied with. It's quite bright and makes the boat easier to find in an achorage. It'll be on the boat as long as it works!

Re: LED Anchor Light

Why can't I just buy one of these and plug it in my already available anchor plug?

The low-cost LEDs and unfortunately some of the high priced LEDs give off a lot of RF noise, interfering with VHF radios. For 8 bucks you can try it out.

Thanks, figure I'll give it a shot.

Re: LED Anchor Light

I had really good luck with an innovative lighting LED all around light for anchor on my last ketch.

Although not technically legal, I plan to use just this on the masthead and deck mounted vow light on my new cat. When inshore, I'll use both when underway and offshore will use just the white all around unless I sight other vessels.

In the pacific, prior to LEDs I used a 10w anchor 25 w tricolor combo. When sailing far offshore, I would use just the white and switch to the tricolor if sighted traffic. If motoring offshore, I would still display the tricolor unless sighting another vessel.

I think being seen is the most important issue and most of us are planning to give way to large ships anyway, whether we are under sail or power.

Please reconsider this plan.

This sort of practice used to be used in the days before LEDs / tricolours were commonplace. It produced a few tense moments trying to ascertain the direction of travel of another sailboat.

These days with low power relatively inexpensive LEDs there is really no excuse.
