I have been in the process of replacing all the interior light bulbs with LEDs,
and am now moving on to the navigation lights. For my bow navigation lights,
I'm probably going to go with Marinebeam, as I could not find high-intensity
green 1157 LEDs. There are plenty of red ones out there (think automotive turn
signal bulbs), but not much in the way of bright green ones. I'm just waiting
to hear back from them with confirmation of the lumens produced by their bulbs.
As for the rest of the bulbs (and I will include the stern light in this
comment because the Marinebeam light for the stern is going to be TOO bright),
there are plenty of versions of festoon/automotive 12v LED bulbs out there, and
many come in packages of 10 or more for somewhere around $15.
The key is is look for lumens, and compare them to the bulb you are replacing.
It takes a little bit of research, but by poking around the net you can find
out how many lumens your current bulb puts out, consider whether you want your
light to be brighter (usually that is the case), and also consider the color of
the white light. I found that most of the time when it says "warm white", that
amounts to 3000K, which was spot-on equivalent to the halogen bulbs I was
replacing. You may want to go all the way to a bright white (6000K) for the
stern light for the sake of aiding visibility, but I think that's a little too
white for interior lights.
As for the festoon bulbs, measure the length in mm, and search for them that
way - don't worry, you'll find them.
I also ended up putting a bright dome lamp in my engine compartment, and I had
some strips of white LEDs, and now I can work on my engine without a
flashlight. That's been a great addition.
So far I can turn on every light in the boat and draw no more than 3 amps, and
there's a lot of lights in our C&C 37/40+

Subject: Re: Stus-List changing stern light & converting nav lights to LEDs?
Well it can be a bit of a search for a correct bulb, at reasonable price, and
the manufacturers often don't always give very clear info.
I've been looking at LED festoon bulbs to convert a new Perko horizontal mount
stern light on my 27 (the small 'dome' type), mounted in the teak trim on the
stern. Previous owner had replaced the dome on the original fitting (same style
as the Perko) with a all-round one (!), and the light itself was pretty
deteriorated. So the bulb is 31mm 'type 71', not the larger, much more common,
42mm.
I've found Dr. LED bulbs at $40+ (CAD) (part number 9000173) that are clearly
identified as a nav light replacement. Then there is the Victory SourceLED at
$16 that is only identified as 'for Perko lights'. I'll probably go for the
Dr. LED. At least I found an unused Perko fixture at a marine consignment shop
for $22, rather than the $75 I was quoted otherwise.
By the way, I looked at the Victory stern lights of the same style. Couldn't
find a LED socket-type bulb that would fit. And the Sea Dog versions you find
all over the place (which I think would have the same issue with LED bulbs)
have not been tested to international standards.
