Before I make another abortive trip up the mast... What is the shape/type of bulb used for standard Jeanneau masthead anchor lamps. We've been using ours a lot recently and I would like to replace it with a low current LED. Almost all the other lamps on board are converted, but not the anchor lamp. I suspect a double ended festoon bulb??? 38mm or 42mm? Which?
I remember that the dealer in Largs couldn't confirm the exact type of bulb. It's possible that Jeanneau didn't always fit the same type.
I went up the mast and discovered that my unit was from Aquasignal and think it was type 25. I do remember that their spec. said only suitable for boats up to 12m and so my 2009 42DS should have had the next model in the range. I expect Jeanneau probably skimped in 42DS & 42I.
I bought one from ultraleds.co.uk and the order says "1 x Aquasignal Festoon Dimpled Ends 12v 10W CW (UAQ12CW)". Unfortunately, I can't find it on their website now. It certainly is a festoon bulb with dimpled ends (think it is also called DIN Festoon).
I do have a spare and will try to find it to measure and also find out where I bought it.
UPDATE: I found the order to the spare "Aquasignal Festoon Dimpled Ends 12v 8W WW (UAQ12WW)". Only 8W vs. the original 10W. An internet search indicated it might be similar to one sold here bedazzledledlighting.co.uk/product/festoon-42mm-12-led-dimple/. This is equiv. to 15W vs. 8W or 10W, so a better output.
I will try to find the spare and check measurements.
if you pm me I can send you a picture of mine (I have a 2007 42i) I replace mine with a dusk to dawn led from these folk were very helpful and was able to identify from the picture what bulb I required
