For my Aqua Signal Tri-color I am using just white DR LED replacement LED bulbs which saved me about 40$ buying just the white ones (over the colored) and the perceived look is just fine...

BTW Dr LED has been active with the local boatshows and you can save some $$ when ordering just mentioning a boat show you went to...

My bow light kept getting dunked and water got into it, causing it to fail. I'm looking to replace the whole thing anyway, ideally with something that can withstand getting dunked repeatedly. Thanks for the useful information.

I'm reading lots of reports of people who did this very thing and ended up with pink and blue nav lights. All the recommendations I ran across while researching the same thing were pretty adamant about using red LED's port and green LED's starboard. YMMV.

We've got a new OrcaGreen anchor/tri-color LED showing up in the next week or so. Best part about those is that you can use one set of wires (+/-) to run both lights. Sweet.

Be aware that the only Dr. LED replacement bulb that is currently USCG certified is their Aqua Signal 40 Anchor light replacement bulb.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I did some quick checking on the light spectrum of white LEDs. While I'm posting an early "find" and not necessarily the spectrum of the white LEDs that are for sale for Marine use, you can see from this chart that it would be pretty easy to imagine a replacement white LED that would not produce green light and would appear blue instead, when run through your existing green filter.



Green light has a wavelength of about 510 nm.
Red light has a wavelength of about 650 nm.



Jut because it looks white, doesn't mean there has to be a lot of green light being emitted.

Same goes for red filters making the light look pink instead. There's very little red being produced in the above chart.

By comparison, an incandescent bulb has tons of green and red to work with, so using red or green filters would work well (as we know).

All this has me thinking that maybe I ought to buy separate bow lights, using LEDs made specifically for Red and Green, individually. (Manufacturers make LEDs with certain colors using certain chemicals inside the LED.) It seems like the best way to get the brightness that I want. It would take a custom bracket.

never mind, read the last post - looks like using "clear" LED lights with a filtering lense may not be a good idea. I'll wait and see how your project goes, then - hopefully you'll share your results with us.

Anybody know of good options for installing LED nav lights in the below-deck-line flush-mount positions? I.e. replacing these:



I've noticed most nav LEDs are way too big, so maybe I'm outta luck and should go with the sort of deck mount that you guys are talking about?

Janders - I'm interested in hearing about your OrcaGreen experiences... I'm thinking about buying the unit too. Right now we just have deck level bow/stern lights and a 2-wire anchor light at the masthead. The fact that you don't have to run a third wire up the mast for the OrcaGreen units looks intriguing...

Adam,

Didn't forget about your question. I looked on Google using the 3 search words: "LED navigation lights" (without the quotes). This led (no pun indended!) to some good hits. I also foraged around the Aqua Marine website. They have a series 31 (good to 1nm) and a series 32 (good to 2nm). The series 32 is at the link that Sailingdog posted.

I also googled for even brighter lights by googling: "LED navigation lights -2nm" (with no quotes). I didn't find any red or green high intensity lights that way, at least not in the time I devoted to it. I did find a 3nm white light though, I think from OrcaGreen, IIRC.

Regards
